The two biggest complaints I have are how the character moved and the inclusion of a timer. First of all your character moves so painfully slow. It feels like you're sloggi,ng through mud or something. His walk speed is just ridiculous. And then there's the level timer. Each section has a timer where you have to complete it in a certain amount of time. You do get plenty of time, I never ran out, but on my first play through it made me feel kinda rushed, and in a game where jumps need to be timed just right I really don't care for that.
Still though, those are relatively small complaints and never really ruined the experience for me. So I would say you should definitely check this out. I give it a solid four stakes to the heart out of five.
