Super cool idea! I know this is a small detail but that menu screen to gameplay transition felt really nice. I also was pretty impressed by the animations on the crabs. Some of my feedback would be to make the cannon sound effect different. It kinda sounds like a lazer gun and i think if it was more of a powerful cannon sound it could really add to the feel of the game. I also think the controls were a little awkward for shooting. Using WASD to move the cannon i like because it makes aiming more challenging, however i think the shoot keybind would have been better as a mouse button or space. Another thing i liked though was the map in the top right. The map was a great idea. Great Job making an awesome game!
