Downloaded this the other week... its fun. Not amazingly so, but the game feels fun and unique.
The algorithm for generating the levels must be quite clever as they seem perfectly tuned for playing through with natural momentum... ie. the moment the level starts, you should get going if you want to avoid most traps / obstacles. After playing for a while, you find yourself beating levels that would have looked insane / impossible to you at first. Having said that, the hardest difficulty level generation is still stupidly hard.
There's a bit of variance in there that means you can't just use constant momentum through every level -- sometimes it'll have you pausing or travelling at different paces. Sometimes you have to 'use' a few lives to figure out the way a level works, and if lucks on your side you'll gain them back through pick-ups. For the game to be able to generate levels that also work with 'Wheel Bob', the shmup aircraft thing and the double jump / jetback guys --- I just think the random level generation is really clever.
