The idea here is great--it takes the original comic and redesigns it to fit a a gameplay format. I also love how the stickman "runs" to the beat (at least with song C and A--not as much in B).
As much as I usually enjoy randomization in games, I thought it hindered this one. It created situations where I had to get damaged by something even if I didn't want to--it would have been cool to try and complete a track without taking damage, and I would've felt awesome doing it! But in every track there was always more than one obstacle where I had to take damage.
Also, I like the idea that the head takes more damage than the limbs, as it adds a tactical element to the game, but players who don't read the description are going to have no clue why damage increases for them at points.
So overall, I enjoyed this. I'm glad to see you plan to update it, as that would be good to see. Nice job with this. :)
