Thoroughly enjoyed the game, could definitely see myself continuing to play it, but had a weird (maybe expected or not) bug that the game no longer allowed me to progress after a certain amount of levels, the door opened but I did not progress to the next room. Also I think background music could be a great quick little addition, but the audio effects were nice. Also, I'm not sure if I was just unlucky but there seemed to be a greater probability to get health rather than fighting bosses, I really wanted to test out the weapons but I rarely saw many bosses. In summary, I think this game was really simple yet extremely fun, and I also love the changing of textures on the tiles.
