very good indeed , made me actually use my head . A very good puzzle game .
Also level 25 was brilliant =D
I found it to be quite challenging for its simple design. It makes me realize how often I take a combination of physics and thought process for granted.
I like the idea, but it's difficult to play
I always love puzzles game that have more than 1 way to complete the level because it gives more replay value .
Very good Game. Love it.
