Downloaded this game yesterday and it's really good. Great music, and challenging gameplay. You have to collect sparks to unlock the exit while various hazards fly through the levels, from water that messes up your handling to dirt that slows you down and dangerous fire. However you're not completely helpless. Besides the need to evade the obstacles, you also have a handful of special abilities like teleporting and a speed boost.
There's a nice amount of levels and the second world starts adding new puzzle elements like ice blocks that have to pushed out of the way to maneuver. Similar to Colossatron, beating a world unlocks an endless survival mode for that chapter. The game was also recently updated with a new chapter so it seems like the developer has plans for post-release support
Controls are tilt or virtual joystick, with buttons to activate your abilities. Haven't tried tilt, but the joystick works well enough. I only wish it was floating.
Don't miss out on this fun game.
