This was a good little game though I kept dying when I jumped and im not sure why. The suprise breaking platforms was a nice touch. Im going to give it a few more tries now as the sound didnt work for me but i just read a comment that it does have sound.
Edit: Ok so I tried it a few more times and didnt seem to have the same issues. I got the sound working and it made a massive difference to the feel of the game especially hearing the music slow down. It got more fun the more I played it. I think something that would improve it is a slightly larger playing area so you so if you get a difficult run you have a bit more time to think (I think the reason I was dying so much when I was jumping is because I was too close to the top. also, are the breaking blocks actually random or are they when you land after a long jump because i noticed they seemed to break more often if i jumped from the top of the screen all the way to the bottom.

Fun game! The idea was very enjoyable and the movement felt nice and fun to use! One problem is that the game is a bit too dificult, this could be because the player falls to fast, you could add a constraint on how fast the player moves. But overall, I really enjoyed it :)

Cool game, nice implementation of the 2nd dimension. The graphics have their charm, I like them, the gameplay has a nice loop and it is addicting, the sounds work for this type of game. Nice game 7/10 overall. (Cloud)
