How to play

1. Click on pieces to remove them. The ones on top will fall and a new one will appear at the top.
2. Align 2x2 pieces of the same type in a square to 'grow' them into a single piece double the size.
3. 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.
