Great game with a very unique concept! I find the control very clunky though, I have to navigate the cat with cannon with Arrow Keys + Space, but also use the mouse simultaneously to place food, perhaps assigning hotkeys to various food (for e.g. 1 -7). I am also not entirely sure what contributes to the Arch Cat Energy bar increasing and how i can make it increase faster. When i finally get the boss to spawn, i think it disappeared so i didn't manage to fight it too. But overall really good job on this game!
EDIT: I realized you can fire coconuts with LMB too, that made the control much better. Ignore previous comments about the control.
