Miniworld

The build tool can be equipped from the Start menu, just select "Tool". If you've played before, you'll need to generate a new map to see new features. That's also in the Start menu.

A: Build / remove / interact with door (when tool not equipped)

B: Jump

Up: Move tool up

Down: Move tool down

Select + Right: Cycle materials forward

Select + Left: Cycle materials backward

Select + Up: Change tool size

Select + Down: Change editing layer (white border = foreground, black = background)

Start: Menu

The controls are very clunky, the GB is a bit short on buttons for this kind of game.
