I liked the art style and music. I did have a little trouble controlling the character and the rail-grinding was a little glitchy at times. It killed my momentum a couple times where the jump to ground was a little short. The first time I died, but the second I used the dash ability and was able to make it. The game is definitely fun to play. I agree with raptor, it might work better to just do a platform/racer where you can just speed through the levels with collectibles or ability upgrades? Speeding around and rail-grinding is more fun than the fighting.
Nice work! Can't wait to see more!
