I think this is a good game: very well thought out. However there are a few drawbacks:
- A consistent art style would be nice: all of the pixel art is different resolutions and there is no prevailing colour scheme. This could be fixed by adding a similar texture pack to the one you used in sprint one - this was much better.
- Also I think that all of the platforms and the character could be bigger - they are supposed to be the main feature of the game, yet are dwarfed by the UI.
- Finally I think that you should spend some time playing around with the friction and the other variables related to the character control. This might make the game feel a lot better compared the current system which doesnt yet have a nice feel.
On the whole, good game.
