The movement for me is way too slow, and it's very confusing on what you're supposed to do, it took me a while to figure out i wasted a bullet, since the icons at the bottom left resemble hieroglyphs, which I now know is an inventory? Also if you walk into a wall, you 'climb' it, trip and at that point you can't control the cube at all as it continues spinning endlessly. I'd recommend speeding the movement up so you don't have to wait ages to move to a next tile, and slowly introducing the features in-game(like telling the player they're supposed to shoot the red thing and other stuff) rather than a block of text. I liked the idea and the graphics though!
