Hi! Congrats for publishing a game!
In its conception, I'm sorry but the game isn't fitting the theme. There are some good ideas here nonetheless, such as the different firing modes you have implemented here.
I felt the game being rapidly out of control for an average player like me: too many things on screen, no clear indication of where you are, camera not following the tank, etc.
Sprites are okay-ish, not fan of pixel art games not having the same pixel ratio accross all of the items (e.g. planes are having way bigger pixels than the rest).
