The gameplay was ok, once I found out how to play
The instructions were not detailed enough to tell how to effectively play this game. It said "move here" for this color "move here" for that color but nothing specific was said such as what you had to move, where the crabs would come from and how big exactly the circles had to be to catch a crab.
The gameplay and concept were all good. The music and animation were done well also.
I hope you reconfigure the instructions menu so it is easier to read and easier to understand how to play the game.
