This reminded me of the mario bros pvp game but with the added layer of intuitively swapping modes by wrapping around the screen either vertically or horizontally. I think my favorite mode had to either be big or small mode, running around super fast is obviously fun and big mode felt like having an unlimited supply POW block. I also liked how I had to swap out of big mode to go down the level. This was a fun and polished game that I could see being at home on a mobile gaming store. Great job!
