great graphics, I love how it combines many nostalgic moments from games that I played in the past. It's like endless runner mixed with Shadow of the beast and combined with Flashback for good measure :) (there are also other influences I could try guessing - Fractured Soul maybe?). Dynamic, hard but with a good dose of checkpoints as somebody else already mentioned. The keyboard buttons layout could have been better, as people are often more accustomed to jump with Space not W or UP arrow. Game's little short, I hope you will do something more with these assets, maybe add some background story. Music is great - so much that it really saddened me that game crashed on ending credits and I couldn't listen to it more (or maybe that's just my computer doing strange things :)).
