I like the graphics and Charakters. The heads reminded me on parodius. The sounds are also pretty solid.
Improvement Points:
- Please add a door indicator it was really hard to find it searched a long time at the start.
- when the character moves its a bit blurry
- add automatic reload when magazine is empty
- items spawned in objects like satelite which i could not pickup
- While shooting you get slowed. I would remove that slowing feels unrewarding
- I lost my spaceship, add a small home indicator
Hope this feedback helps you :D! Keep going!
