Thanks for the feedback. The 'crunchiness' really does make up for at least 60% of the game haha. For the crabs spawning right at the edge of the screen, that's probably an aspect ratio problem. Do you know what aspect ratio you're computer is using?
For the bug you found, the main score does not change even if you smash the crabs after dying so I just didn't bother fixing it haha.
Thanks for playing the game!
