As much fun as this game might be I really cannot give it a positive rating. It's a shame because most of the map designs are pretty good.
The physics feels incredibly inconsistent and quite clunky, sometimes when you should slide on a wall you get knocked straight off of it; the beams feel awful to use; the jump pads don't seem to always apply the same amount of force; and there is very little conservation of momentum which ruins the flow of some sequences.
The controls also feel pretty terrible due to some sort of input delay. A lot of the times I would find myself pressing the space bar and my character not jumping and instead just sliding straight off a wall. Additionally, playing the challenge mode makes you question the size of your hitbox because even if you go straight through the purple orbs, they only register about half of the time.
I know this is not a AAA game but if more care was put into these basic elements it would have been a very enjoyable parkour style speed run game, unfortunately it isn't which makes it a rather frustrating experience.
