Thanks goodness you put that checkpoint in there. This is very hard. I like the music, I like the story element. That makes me want to keep playing. I did find it annoying that touching the spikes when I was on that platform killed me. I think they should only kill you if you land on them. Then you had that one with like 6 spike traps on one platform to jump between :p Also, you really have to maximize your jump distance to get onto some platforms. I saw how you rewind, but not sure that's much different then a start over. This has potential on it's own in general, I'd like to play it again to learn the story but think it needs to be a little bit easier.
