As you ask for feedbacks, i wouldl say there are lots of small problems:
- can't left click after first death (athough it's too weak so i mainly use the right click weapon)
- the normal speed is to slow comparing to enemy's attack so i have to abuse the dashing
- it should should the cursor when pause
- the back clipping can be improved with some alpha dithering
I like that insteading of having a fast bulllet game like most of the submission, you are trying something different. the water environment also looks charming and relaxing
(As It's a small game made with unity, i suggest you to export it in WebGL platform.)
