I'm only 12 levels in, so I don't know about the rest yet, but so far it's been flawless.

Everything I would want from a platformer I want to boil my blood. Only flaw I can really point out is a lack of things like pause screens, but due to time constraints that is understandable.

Overall a very good game that I will play to completion, and then some. I'll be sure to chuck a few quid your way when I get the chance!
