Really interesting game! I really dig the concept (once I worked out what it was haha). I was initially very stumped about what to do, but worked it out eventually. Perhaps some further explaining could be useful. I got to the purple gem at the bottom of the map before stopping. I think it is a tricky game but not impossible. You basically have to fail lots of times to work out the route, but once you know it, you can get back to you place pretty quickly. I think the hardest bit is trying to memorise the other colour platforms. I was almost tempted to take photographs of them all haha. Anyway, really solid concept. I also really liked the music.
