Some faults, but overall good concept.
The concept of the game was really good, and it was nicely done, but still, it could have been done a whole lot better.
When I was running, I could barely see what was in front of me, so I had to slow down to make sure that I saw enough of the gapy I was gonna jump to calculate my jump. If you had added a sort of scrolling minimap that let you see a few 10 meters ahead of where you are, then that would be really great, and make the game alot more gamer friendly.
Also, I found some fault with the programming, for example, when I went back to the main menu after running and falling to a surely painful death, the music started looping. You should probably fix that for later versions of the game.
And the buttons weren't that reactive when I tried to get in on easy and the different types of games.
All in all, good idea, good start, but not good enough as a finished product. Improve it a little more, and we'll see next time c:
