Sponge Blocks

Your objective is to paint wooden blocks using oddly shaped sponges in as few moves as possible. Take your time, there are no time limits, and you can undo moves with no restrictions.

With 10 hand crafted blocks and four* sponges there are 40 combinations to enjoy painting. Or, if you like a challenge, try to match (or beat) the best solutions I could find on each level to be awarded three stars.

*three sponges are unlockable, and have weird shapes (seriously, how would you even use those?)
