The game is decent for what it is, but more importantly there is so much red on this page you're gonna give someone a seizure.
edit: Now I've had a little more time to play it and holy Jesus are some of those challenges insane. The stone pillar is absolutely bonkers and I'll probably never beat the tower of turbo flames.
For future levels, I would like more open level design to run around in. The controls are decent enough but having more room to chain long jumps and build momentum would be fun.
