Nice Game! I really enjoyed the graphics and how the theme was a very prominent game mechanic.
One thing, however, is that the controls from the start were not clear. Neither was the objective, nor the timer. It took me a minute to understand what I was doing, but even then I still never realised there was a double jump, or that you could hang from ledges.
But the graphics were really good. I can tell you put a lot of time into them. I also liked how the level design was symetrical with minor variations, meaning that you could switch from one level to the other with no glitches or great disorientation.
Overall, great game! I would totally recomend this to speedrunners!
