Nice start for your first game on itch! Just some constructive criticism - I wasn't sure if the movement was buggy but strafing the whole time made it difficult for a game whose main mechanics is combat. I then discovered that if I hug the wall a certain way, it would rotate my player, but it seemed more random than something I could replicate consistently, so I ended up just moving against a wall whenever I needed to turn and hoped for the best. Also because the projectile spawns behind the character, if I'm backed against the wall, the wall collides with the projectile, negating it.
Edit: I just read that you can rotate with arrow keys... ok that actually makes the gameplay MUCH better! The tank controls actually felt nice (I didn't need to use up or down since the map is pretty level).
