Interesting side scroller, could use more speed
Not a bad looking or sounding game. The controls work well, and the look reminds me of a classic NES side-scroller with less pixelation.
I think the game could benefit from a bit faster movement, both walking and jumping. As it is you're kind of trudging along, and the jumps are a bit floaty. Also, minor suggestion, but it'd be good to make the characters clickable on the character select screen. I definitely went to click on their pictures before clicking on their text names.
