The assets are beautiful, both visual and audio. However, I would try to bring the clock in the corner to the same resolution as well since it is the only element that is out of line. Of course, you would have to find a way to make the time visible anyway.
The only problem I have with the gameplay is the strength of the vertical jumps in relation to the horizontal jumps. Of course there is gravitation to consider with a vertical jump but I find it feels a little too strong, but that's just one opinion out of many.
In any case, it is a wuder nice game keep up the good work.
