Roll up the world. Everything sticks. Nothing is out of context.
A fan-made homage, rolled together by Claude. Original code, original music, no assets from the real game.

How to Play
Tilt
Tip the top of the phone away from you to roll forward, and back toward you to reverse
‹ ›
Pan the camera. The katamari always rolls the way the camera faces, so you steer by panning while you tilt
DASH
Hold for a burst of speed. You need it to climb — a slope you crawl at will stop you
RECENTRE
Re-zero the tilt to however you are holding the phone now. Use it whenever you shift position
II
Pause. From there you can restart or quit
No motion sensor, or you declined the permission? On-screen ▲ and ▼ arrows
appear in place of RECENTRE and drive the katamari instead. Everything else
is identical.
W A S D
Roll the katamari, always relative to where the camera is looking (arrow keys work too)
Mouse
Swing the camera around
Shift
Dash — costs momentum control
Space
Whip around 180°
Enter
Tap to finish the stage early (once you have hit the goal). Hold it for a moment to abandon the run and go back to the title.
Q / E
Nudge camera left / right
Esc / P
Pause
M
Mute music
R
Restart the stage
Anything smaller than your katamari sticks to it. Every object you collect makes the
ball bigger, which makes bigger things collectable. Long thin things can be picked up
even when they look too big — they will make you roll strangely until you cover them up.
Slamming into something huge at speed will shake objects loose.
The stage does not end when you hit the goal — it ends when the clock does,
and the size you finish at is the size that counts. Once you have passed the goal
you can press Enter to stop early and bank what you have. If you manage to
roll up absolutely everything, the round closes itself.

Automatic picks touch controls on a device with a touchscreen and no mouse.
Override it if you are on a laptop with a touchscreen, or want to try the
phone controls on a desktop.
Clears which stages you have opened, your best sizes and the collection log.
Volume, camera and quality settings are kept. There is no undo, so it asks twice.
