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.)

It's a very nice looking game!, I like how you have multiple projectiles to shoot. However after I died and reset, I could no longer shoot any projectiles. I also found it quite difficult to dodge the projectiles in certain situations.
