Every level, all crabs collected. Such a unique gameplay. Illusion Labs entered the runner genre with quite a runner, a pretty unique as it have you climbing up a spinning tower and collect all the crabs. Always run and tap to jump, hold to jump longer... Seems simple in the beginning but soon evolves into a really tricky game where collecting all crabs will be devious, with multiple paths to go up and some well hidden crabs and new abilities (wall jump). There are many boss fights that enhance gameplay and add pressure, besides making the game more awesome. Its difficult but never frustrating because you cant die, you "only" loose crabs, that are scattered through the level once you get hit... "only"). Its from Illusion Labs (Blast-A-Way, Touchgrind,...) so quality is a given here, it pours quality everywhere. Tons of levels, lots of bosses, different environments, NO IAP, GameCenter with plenty of leaderboards (I'm first on my friends list, where are you now, Andy :P).
One of the most unique runners on the AppStore. And also one of the best. If you like runners and don't own this one, pick it up immediately. Absolutely recommended. Wondering if Illusion Labs is cooking something now...
