Nice take on the evolution theme !
It was so cool seing the progression of graphics and music from classic 8 bit monochrome to full on smooth pre rendered sprites with more Hd music. The fact that you took the time to render and cleanup all these different frames for those different styles to convey the evolution is just Insane !
So i can only applaude :o
Gameplay wise everything works fine, it's a nice autoscroll platformer. My only gripe is that it was a bit confusing at first to guess what was a powerup and what was an obstacle that would hurt you especially on the first segment.
But other than that it was fun to play through till the end, well done :)
