Tap to jump, stick to stuff. Simple, right? You control a squishy blob that can stick to almost anything. Time the moving arrow and tap to jump. Stick your way up terrain, metal beam things, pipes, moving platforms, spinning platforms, and more. wow Be careful, however, as one wrong jump could land you back at the very beginning. The game features two difficulty modes: hard and impossible. Hard mode features checkpoints and an undo move button. Impossible mode has no checkpoints and a faster arrow. But like I'm serious when I say impossible because I doubt anyone will ever complete the game in impossible mode. Keep your cool, improve your jumping skills, and stick with it to the very end.
