Fun concept, the repair mechanic is quite nicely executed, I was a bit confused about the shooting at first, having to hold down the mouse button to shoot further seems a bit of a strange mechanic? The whirlpool,while a cool concept gives me a headache, making the water color a bit more washed out and not have that strong blue to white contrast would make it a bit less nauseating.
The bosses also seem to be way too good at dodging, maybe its just my aim but they are super good at dodging and that is just annoying.
Pretty good submission!
