This was really fun! Addictive enough to have me spend 20 minutes completing all 5 levels.
Suggested areas to work on:
1 - The FPS reduces significantly when battling the tanks and shooting the officers - almost to the point of wondering if the game will crash.
2 - There was 1 prisoner on level 4 who I'm sure was unreachable.
3 - Improved sound effects i.e. different level music, mood music when facing the tanks etc
Additional unexpected behavior:
4 - NPCs were able to shoot through boxes/floors which stopped my bullets.
5 - When dropping off a ledge, it is possible to walk into midair before falling.
Also, like many 2D games, the best way to kill something like the level 1 boss is to scroll it off the screen and spam bullets.
I did not have any performance issues - it was steady at 60fps.
