It was a fun game. I enjoyed the visuals and the audio! I sometimes found that when I shot a projectile, it would immediately despawn, because it collided with the wall in front of me. It made the projectile feel a little weird and clunky.
I also found that when I finished the game, the game did not return to the start menu. There was no way to advance from the "Thanks for playing" screen back to the main menu.
But overall, I really enjoyed it!
