Generally, any mouse press and release will count as a move. Specifically:

- Attaching a ball or balloon
- Detaching a ball or balloon
- Moving a block (one move per click, you can move it as much as you want during that click though)
- Shooting a "3d" ball
- Attaching Pokey or a sticky bomb

Using time-bugs does not decrease your move counter (but you'll still go back one move).

Things that don't count as moves:

- Throwing balls
- Catching balls
