- The game is fun in a simple way
- Buying fire rate seems to decrease the fire rate instead of increase it. Also it would be nice if you could hold LMB to fire continuously
- It would be nice to add impact effects when hitting stuff
- Some of the UI elements are too small on 4k monitor and the UI doesn't scale properly when fullscrened. Also consider using progress indicators for the health rather than numbers as that would be more clear on the first glance
- You really should publish a web build, running random executables is risky
