How it works
1
Build
Tap a block, then paint it onto the grid to make your world — platforms, gems, enemies and a goal.
2
Code
Snap together blocks to set the rules — how the player moves, how enemies behave, and how to win.
3
Play
Hit Play and jump in! Use the arrow keys, or the on-screen buttons on a tablet.
4
Share
Send your game to a friend with a link, a level file, or a playable file they just open and play.
