I went on the outside over the top after picking my weapon my first time lol. There is some text at the top of the screen that is very hard to read and I had to jump and spam click to select my weapon. I had a good time once I went the right way. I normally hate getting stuck on/in walls in 2D platformers, but the way it was used here (I am assuming wall jumping was the intended solution to the med and high jumps) made It fun. Flinging the cube over the top of platforms was really satisfying!
