I like the art and the game seems fun but I had the same problem as the other comment said when entering the square of the right. If you can fix it and reupload it i would like to play it again

The controls were a bit clunky, especially the shots from the gun but I liked the idea. I played the game for a while and hit this when I was at a wall on the right wall. Hope it helps.
