Spectacular! It is such a polished game in such a short time, and with quite a lot of levels! Audio, art, gameplay everything was amazing, really well done!
For the feedback, I have to say that there were some levels where it was possible to jump straight to the finish (of course not easy jumps) skipping the whole stage pretty fast (but I think it is a good thing because it lets you think creatively), also it is possible to glitch trough blue zones, but it actually made the game even more interesting to play, because you were not forced to follow the rules :D
The only thing that made the game a little bit harder was that when you are falling and catch crystal in the mid-air and then instantly press J it doesn't register it that fast and you end up falling to the pit. Despite that, it is one of the best entries, without a doubt!
