I love how the crabs look :D The idea is used to its limits and the diffrent slimes makes the game more interesting. I also noticed the color assist mode wich is a plus for this kind of game great thinking :D
I think the game needs an undo action button becouse sometimes i was so close to solving a puzzle then made a small mistake and had to do it again from start :/
Other than that it was very fun to play this game great puzzles and sound desing amazing job :D
