Not in the game: your saved stages, and any stage you take out. Drag one up to add it
☁ Your stages, stage order and progress are backed up to your Claude account.
Build your own stage: shape the ground, place trees, stars, gems, ladders, teleport pads and more. Save it, play it, or copy its code to share.
Save & share codes
A save code carries your whole game to another device. An island code lets a friend play the same island from scratch.
How to play
Arrows walk. You can climb 1 step and drop any height. Double-tap to dash.
Space pockets the cube in front, or places one. N picks the other option, X grabs the cube under you.
H jumps, J jumps and smashes 3 down. Press an arrow mid-jump to leap onto the next tile.
Face a tree and press Space to shake it: fruit falls, and anything buried under it comes up.
Dark pink bounce blocks fling you 18 high. Space pockets one in front of you, D sets it down.
P punches 3 blocks ahead. G digs with a sand pill. K throws a bomb, L drops one at your feet, M fires the magnet.
Blast a crater in low ground (2 high or less) and water seeps in, filling it to the lowest point of the rim. Plateaus never flood. Swim across, or dive for anything on the bottom.
A / S turn the camera (hold Option/Alt + arrows to orbit smoothly around and up/down), B puts it behind you, V first-person, O overview, \ big map, Z undo, Esc this menu.
Find every star to unlock the next island. Watch for oddities: vaults, sky stars, crumbling causeways, islands split by a chasm or a wide strait (turquoise cubes make bridges), 300-block-long islands and night islands.
