A cool top down shooter! Though there is room for improvement:
- Some guns are flipped the other way around.
- I feel like the game is missing some UI, e.g the health bar, a score bar and e.t.c.
- Some sound effects, visual effects and some music wouldn't hurt the game, it would've made it very more engaging.
Overall, the game is decent, and I suggest you take the suggestions of other people into consideration.
