Why several keys share one action
Space maps to jump, attack, fire and action simultaneously. That looks like a conflict and it is deliberate.
A single physical key can raise several abstract actions, and each game listens only for the ones it uses. A platformer hears Space as 'jump'; an arena game hears it as 'attack'. Neither game knows the other exists.
The benefit is that Space always does the obvious thing in any game on the site, without anybody having to remember which game uses which key. Games that need both jumping and attacking simultaneously — Monster Arcade Ultimate — put attack on the mouse and J instead.
Movement schemes
Both arrows and WASD work everywhere, always, with no setting to change. That covers the two conventions people arrive with and costs nothing to support.
Diagonal movement is normalised to length one in top-down games, so moving diagonally is not faster than moving straight. Where a game has a virtual stick on touch, keyboard input and stick input are summed and then clamped, which means a player using both never exceeds normal speed.
Details that matter for accessibility
- Keys never fire while typing. Input is ignored when focus is in a text field, so the search box works normally on a game page.
- Arrow keys and Space are only swallowed inside the play area. Page scrolling works normally everywhere else.
- Held keys release on blur. Alt-tabbing away never leaves an input stuck on.
- Key repeat is ignored. Holding a key produces one press event, not a stream, so buffered jumps behave predictably.
- Every overlay button is keyboard reachable and takes focus when a screen appears, so a keyboard player never has to hunt for Start.
Mouse use
Three games use the mouse meaningfully. The arena games use it for aiming, with the mouse button as an alternative attack. Monster Cannon Challenge uses drag-to-aim, where the direction sets the angle and the distance sets the power.
Everywhere else the mouse is optional. Every game on the site is fully playable with the keyboard alone, which is a deliberate constraint rather than a coincidence — a game that requires a mouse excludes anybody who cannot use one comfortably.
Keys that are not gameplay
Two bindings work the same way in every game on the site, and they are worth committing to memory because they are the ones you reach for under pressure.
- P or Escape pauses, and pressing either again resumes. The loop stops rather than merely hiding — nothing advances while you are paused, so it is safe to walk away mid-run.
- R restarts, but only from the game-over screen, the win screen or while paused. It deliberately does nothing during play, so a mistimed key press cannot end a run you were winning. To restart mid-run, pause first.
Sound is not on a key. It is the speaker button above the stage, which is a focusable control like any other — so tabbing to it and pressing Space works if your hands are already on the keyboard. It is worth finding: audio cues carry real information in the boss fights, and playing muted by accident is the most common self-inflicted handicap here.
Browser shortcuts are never intercepted. Ctrl and Alt combinations, F-keys and tab switching all behave exactly as they normally would, because a game that captures those is a game you cannot leave.
Playing with one hand on a keyboard
Several games here are comfortable with one hand on a keyboard, which is worth knowing if you are eating.
The arrow cluster plus the right Shift key covers movement, jump, slide and dash on its own, which makes every runner and every platformer playable right-handed without moving.
On the left, WASD plus the left Shift key does the same. Space is reachable from either. That redundancy is the main reason both schemes exist rather than one being a courtesy to the other.
Why two schemes exist
Every game accepts both arrow keys and WASD, and both cover the full action set rather than one being a partial alternative.
The reason is hand preference rather than convention. Right-handed players frequently prefer the arrow cluster because it sits under the dominant hand; left-handed players and anyone used to first-person games prefer WASD. Neither is correct and forcing either is an unnecessary barrier.
Space and the Shift keys are shared between the two, so a player can mix — arrows for movement, left Shift for dash — without anything breaking. The input layer maps keys to actions rather than actions to keys, which is what makes that work.
The one thing to be aware of is keyboard ghosting: cheaper keyboards cannot register certain three-key combinations simultaneously. If a specific combination reliably fails in a game that needs movement plus two actions, switching schemes usually solves it, because the alternative keys sit in a different part of the matrix.
Using a gamepad
Gamepads are not directly supported, and there is an honest workaround worth knowing about.
The games read keyboard and pointer input only — there is no Gamepad API integration. What works is third-party software that maps a controller to keyboard keys, which the games then receive as ordinary key presses and handle normally.
That is a genuine solution rather than a fudge, since the input layer maps keys to actions rather than the reverse. It is also not something we can support or troubleshoot, and native gamepad handling sits on the list of things not currently built rather than things quietly assumed to work.
Key takeaways
- Arrows and WASD both work everywhere; Space is the general-purpose action key.
- One physical key can raise several abstract actions, so Space always does the obvious thing.
- Keys never fire while typing, release on blur, and ignore key repeat.
- Every game is fully playable with the keyboard alone — the mouse is never required.
Frequently asked questions
Can I remap the controls?
Not currently. Both arrows and WASD work everywhere, and most actions have two or three alternative keys, which covers most needs without a settings screen.
Why does Space do different things in different games?
It maps to several abstract actions at once, and each game listens only for the ones it uses. The result is that Space always does the obvious thing.
Do I need a mouse?
No. Every game is fully playable with the keyboard alone.
Can I remap the keys?
Why does one specific key combination not register?
