The game is polished and the controls are responsive.
Where I feel it falls short is when it comes to the jump. I don't know if that's supposed to be apart of the challenge, but the character feels heavy. That might be a bit too nitpicky, and it didn't prevent me from progressing, but I do feel this may turn some players off.
I also find that the music constantly looping like that can get to you after while. Don't get me wrong, it's great music, but it's such a short loop, that eventually the track will start to bother you. With that said, the inclusion of different tracks, a way to turn the music off, or at least a break in the music loop between levels would be a great idea.
I personally think the transition between levels takes a bit too long, but again, that might just be too nitpicky.
Overally, the game is pretty solid, and I think you got the look and feel you were going for, but I didn't get a "craziest" vibe from this one.
Thanks for sharing.
