At A Glance
MONOMOON (Steam app 3285880, Gentle Giant) is a single-player puzzle you learn by moving. This MONOMOON beginner guide covers the opening hour: keyboard movement, the mouse moon, the first book, and the first checkpoint. Verified November 13, 2026 · Steam.
About ten hours can reach a credits layer. Hidden routes stay open after that. On Launch · hotfix 1.0.10, a sealed path is a missing page or a moon you have not parked.

How do I move in the opening hour?
The keyboard owns the body. Walk, jump, wall-jump, and roll are the opening kit, and a downward input on a wall lets you slide. The mouse owns the moon and nothing else. MONOMOON has no attack button, no weapon, and no enemy health bar. A ledge you cannot clear is a route, a roll, or a flower that is still dark.
Steam lists full controller support. Aim is finer on a mouse. A pad hold to keep the moon active is Unverified. Play the first room on keyboard and mouse, then rebind only if a finger cannot reach a key. Trust the pause menu over any keymap written outside the game.
Read the room before you hunt an upgrade
Bounce pads are real in the opening stretch. A short hop onto the pad beats a running jump that overshoots it. Death pits are real too: a fall that kills you returns you to the last checkpoint you activated.
Wall-jump is already in the base kit. A height you still cannot make after a wall-jump wants a flower row inside the moon's light, or a path from the other side. A second jump is Unverified. The next section is the book that records the roll once you use it.
What is the first book for?
The Tome is the book. The first one you can open starts as a single page in a language the game does not translate. Important objects pick up a highlight. The book stays available after you leave the spot where you found it.
Later leaves are found in the world. A blank leaf means that page is still out there. It does not mean the puzzle that wants the leaf is optional. Copy marks into your own notes when a gate repeats them. This site will not invent a translation.
What the opening actually shows
The opening presents a broken moon and a row of symbols, each one standing for a different thing. An early gate carries a short moon line and a piece count. The exact sentence is Unverified. Read the gate and keep the words on the stone.
Some interiors wake when you rotate a control until the lights change. After that, walk the outside edge again. A path you passed while the room was dark can be live. A lock with a small button in the frame is the same idea: search the frame before you call the door a progression gate. With the first page stored, the save that protects the experiment is a checkpoint.
When do I activate a checkpoint?
Touch a checkpoint before a long drop, a dark well, or any room whose floor you have not tested. Once it is live you can return to it from the map. An unlit checkpoint is a save you have not taken. Death sends you to the last one you activated, so a pit behind an unlit checkpoint costs the whole walk back.
Another checkpoint can sit deeper in, after a machine comes on. Light the one in the doorway first, then the one past the mechanism. The pause menu also keeps a timer. Use it to pace yourself. MONOMOON does not name the next room.
What a failed jump is allowed to cost
With a checkpoint lit, a missed bounce or a bad slide is one reload. Use that cheap failure to test the roll and the slide before you leave the room. If the same gap still refuses every base move, the block is information: a symbol, a dark flower, or a page.
That split — body versus information — is the decision in the next section. Run the table before you go looking for a move the keyboard does not have.
What should I try before a new move?
Use this table in the room. It maps what you see to the tool you already have. The hotfix list comes after it, once the base kit has actually failed.
| You see | Treat it as | Do this |
|---|---|---|
| A ledge the jump will not clear | Route or light | Wall-jump, then put the moon on the flower row. Try the other side of the room |
| A narrow gap | The roll | Roll once. Open the Tome and confirm the move was written down |
| A wall you stick to | A slide | Press down and leave the wall. The slide is in the opening kit |
| A flower that stays dark | Moon radius | Lower sensitivity and park the light. Detail on the moon guide |
| A cold brazier | An early limit | Leave it. A later item lights braziers across the map. The item name is TBA |
| A moon mark on a door | Placement | Park the moon on the mark. If the door stays shut, leave it for a matching page |
| A bounce pad you fly past | Timing | Short hop onto the pad. A running jump overshoots |
| A sealed path on the right | Patch or page | Check the build in the next section before you grind the wall |
The roll is a rule, not a dodge
The Tome records the roll because the move has more than one use. A gap you keep jumping at is often a roll you have not committed to. Open the book after the first clean roll so you know the game agrees the move exists.
Flowers follow the moon's radius, not a click on the bloom. If the light will not sit still, drop sensitivity, stop the character, and park the cursor. Spam-clicking the flower does not replace that. Once the body can reach the switch, the moon has to stay put while you run. That is the next rule.
Can the moon stay on a switch?
The moon can lock onto a target and stay there while you move. Hovering is a different gesture: the light follows the cursor and drops off as soon as you run. On a timed mechanism, park first, then start the clock, then move the character. If the light comes with you, it was never attached.
The room where you first need this has no stable public name on this page (Unverified). The rule travels. Any switch, flower, or moon-marked door that must stay lit during a run wants the same park. Dragging a locked moon away fails until you release it. The release bind is Unverified — confirm it in the menu, and do not invent a key from a guess.
The same park steers a creature
Some creatures move away from the moonlight. You can steer them onto a step or off a ledge. There is still no combat: you are placing light, and the creature is solving a gap. Personal names for those creatures are not published. The goat in the hotfix notes is a creature type, not a named character.
If the moon is parked and the path is still sealed, you are past movement. The next section separates a bad build from a page you have not found.
How do I tell a hotfix from a missing page?
Update before you call a room a softlock. Hotfix 1.0.08 fixed goat interaction at high frame rates, a stuck lilypad edge, stuck pressure plates, and a right-side map spot that looked sealed. That right-side spot was a knowledge gate. The patch changed the geometry so players would stop treating it as a dead end. In a narrow goat gap on a current build, keep moving through; the old high-FPS break is the bug, and the goat itself can still be the puzzle.
Hotfix 1.0.10 fixes more softlocks, adds a VSync toggle, and stops a crash when you die on a bad collision. Turn VSync on when the picture tears. A crash on a fatal fall means the build is older than 1.0.10. After you are on Launch · hotfix 1.0.10, a stuck spot you can describe with a symbol is a missing Tome page.
- Do01Confirm the build is hotfix 1.0.10 or newer before you file a softlock
- Do02Name the missing thing: a Tome page, a moon park, a telescope, or a dark flower
- Do03If the only words you have are "a red door", leave the digits and open an observatory first
- Do04On a lilypad edge, a pressure plate, or a goat that will not release, update to 1.0.08 or newer, then retry the interaction
- Do05On the right side of the map, update to 1.0.08 or newer, then look for a page or a telescope path
- Do06If a fall closes the game, install 1.0.10 and retry the drop from the checkpoint
- Do07Copy the gate text yourself. Exact early sentences on this page are Unverified where captions disagree
A clean stuck report
Write four lines: build number, what the moon is parked on, which Tome leaves are blank, and whether a checkpoint is lit behind you. That list tells you whether the next click is the Steam update or a walk back to a telescope.
When those lines are clean, drill the radius on the moon guide. Door order lives on the walkthrough.
What next
Park the light and set the radius on the moon guide. Do that before you rebind the mouse.
Observatory order, the moon-marked door, and the hotfix-or-page check are on the walkthrough. It stays light on spoilers and does not print red-door digits.
When a symbol will not match, use the puzzle guide and the Tome.
Deck notes and the trigger-held moon are on the controls guide.
FAQ
How long is the opening layer?
About 10 hours to a credits layer, then hidden routes. Puzzle pace varies. The pause-menu timer is your own clock, not a limit.
Why can I not light the braziers?
Early on you cannot make fire. A later item or ability lights the braziers across the map. The item name is TBA.
Does the goat have a name?
No published personal name. It is a creature. High frame rates could break the interaction before hotfix 1.0.08. Do not invent a speaker or a quest giver.
Can I play on a controller?
Yes. Keyboard and mouse recommended · controller supported, not ideal. Lower moon sensitivity if the light will not sit on a flower. A trigger hold to keep the moon active is Unverified.
What should I open after this beginner guide?
The moon guide, then the walkthrough when a door wants a telescope.
