2/10 potatoes. The game is playable, but not really fair or fun. The levels just don't make sense- the places you die in and the places you're supposed to go aren't clear. In level 2, I assumed the game was meant to be a "hunt the hidden collectible" thingy, and was ready to explore, but kept dying out of nowhere.
After figuring out the game wasn't glitching (there were just invisible death fields that weren't marked, at all, even where an infinite pit would have far more sense than apparently normal ground), I found out I was playing a heavily linear platformer where I couldn't see where I was going, at all. In level 3 I died several times trying to drop in platforms I couldn't see.
Speaking of level 3, was it too hard to differentiate the platforms who you can climb from the ones you can't? If it was a puzzle, it failed, there was no logic. If it wasn't it was cheap design.
level four wasn't really funny.
[EDIT]: 2 extra potatoes for making death zones red. 4/10.
