As they say, once you got your first satisfied customers, it gets easy :-) I agree with the other commenters, a solid mechanic, well done in nine hours! Keep on coding!

It took me way too long to figure out that fish surround the playing field, and are not just all at the opening with the cylinders. It's pretty fun to see how optimized I can make my movements, but a few times I've gotten stuck between a block and a cylinder and it prevents me from moving until I get the game over.

I think it's a bit difficult as the customers travel a bit fast for the fish. Could be a pretty cool game if assets were added.
