Not bad but a few complaints. Overall the visuals are okay but....it feels like pixels scattered around too much rather than following a pattern. The HP bar looks nice though, but having at the bottom feels a bit...strange. It's a bit too big mainly, keeps my eyes looking away from the character. I like how the first boss looked though. But the yellow pipes feel stolen from Mario.
I like the mechanics of this game though, good programming, but I feel this game's potential is hardly seen here, could use a lot more than what it's offering, but not bad for a start. The music is alright.
