Very sleek! The tutorial is quite elegant as well.
The gameplay has a very "one more try" energy to it, making me try more times than I'd originally planned (but also, I kept dying by running into things over and over, which made me think I could surely do better than that). My best run was only a couple of seconds over the 1 minute mark, which I imagine is not that great, ha
The controller support is nice, and I appreciated the little health pickups!
I'd have liked some more feedback about what happened when I lost (i.e. did I lose all my health, or did I run out of time?), but it's a minor gripe, really.
Also, the music is great, and the art style, while simple, looks quite polished!
