How to play
- Click on pieces to remove them. The ones on top will fall and a new one will appear at the top.
- Align 2x2 pieces of the same type in a square to 'grow' them into a single piece double the size.
- A level is solved when there is only one piece covering the whole board.
Pieces cannot be removed if:
- The ones on top won't be able to fall properly (misaligned or bigger pieces).
- They have neighbours of the same type next to them, aligned either in the same columns or rows.
