The animation are nice. And the controls are okay...
But, The Enemy AI needs to be improved. I believe that is mostly because running out of time for the jam, but in those kind of cases you try to make gameplay more fun with what you have ready for the jam build.
Like in this case, the gameplay is really slow, even for a turn based game. That's mostly because you have to keep chasing the crabs and then also require to hit it 3-4 times. The gameplay could have been improved just by reducing the enemy health(1-2 hit) for this build. That would have fasten the game pace and give the player a more feel of progression.
Also, the confirm key could be bound to something else other then right mouse button. It just force the player to keep his hand on the mouse for no other use than that.
