The game was generally playable without any problems, although for some reason the movement input sometimes went in the opposite direction. I was a little surprised when the bow and arrow soldiers suddenly appeared. Good job!
when the controls invert,your in a block/border allowing you to go through walls !!! i decided to keep this silly bug(or i was to lazy to fix it).
also,did you get to the boss?and im constantly updating the game.did you try endless?it is fun for airplane trips
