This game just feeeeels jazzzzy and fun!  I like it! :D

I had fun, But the character moves way too fast. But overall it was a great game. thanks for making it.

Made it to the top, but it wasn't easy!

These blocks sure are slippery! I would maybe add a bit of angular and linear drag in the cube's physics to make the player feel more in control (although who's in control when JAZZ IS A-PLAYIN' :D)

Very good music taste in my opinion. It did fit the colors and the craziness of the environment without being too annoying.

Now I'm just a bit sad that I got all the way to the top and nothing happened (apart from my heart skipping a beat each jump). You could have turned this into a game in an instant, even if it's just one level. I hope you consider this for the next one!

Hope this helps, take care!

OMG 382Mb! That sure is big, mate!
EDIT: What the falaffel? How can a game so simple be 382Mb? x'D
Jokes aside, I'm really intrigued about how in the earth did you make it so that the game weighs that much. :|c
Also, I fell down the stage, the cube disappeared and couldn't do anything more...
