As some of the other reviews have said, punishingly hard from very early on, slippery movement with precision platforming leads to frustration anyway. Some zones having aggressively positioned enemies you will die to over and over, makes the no-lives the only way this game isn't just entirely for masochists that want to learn to play a game without having to look at it, but still leaves you throwing yourself at the same run over and over, exacerbated by many areas needing specific upgrades to be completed which you lose on hit.
