Very nicely done! The core mechanics are solid and you're level is designed to show off a lot of tricks, which makes it a great prototype. Going forward i would recommend a few things: Design-wise, stick to the core and try to not use all the tricks in one level (if you do levels) or work on the pacing and difficulty curve as the level progresses if it's an infinite runner. only add new mechanics when you've explored the core mechanics completely. As for the art, FIX IT! you guys are great but the art isn't on the same level as the rest of the game. either work more on your art skills or get an artist on board. The music is nice but i think you can also do better with more time :) looking forward to seeing this on my phone soon.
