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.
