I thought this was a unique game. Couple of thoughts:
+ I thought your idea of someone traveling though time and allowing the player to change the time was interesting.
+ I like the art style and scenery that you're going for.
- I think the game relies too heavily on trial and error and split-second mechanics. This led to a few moments were I had to repeat sections and that was dull.
- I also think the retro time span has a bit too strong of a tint effect.
