This was a really fun game. At first it was difficult to get used to the movement and the way you have to align the crabs, but the more I played the easier it got.
The puzzles are pretty challenging, but still engaging. It was also awesome how you slowly introduced new elements and strategies and slowly ramped them up instead of just dropping the player in and expecting them to immediatelly understand everything.
This was enjoyable, keep up the good work :D
