Hop your creature diagonally across the pyramid: swipe anywhere, use the arrow keys, Q/E/A/D, the numpad diagonals, a gamepad, or the on-screen diamond (Settings › Touch › Buttons). Tap a cube next to you to hop straight there.

Every landing changes a cube's colour. Flip all 28 cubes to the glowing target colour shown in the HUD to clear the round. Early rounds set the target in one hop; later ones need two, and the hardest rounds toggle back and forth.

Watch the drop. A red ball kills on contact. A purple ball hatches into a snake that hunts you — lure it onto a spinning disc's launch cube and it falls off the edge for a big bonus. A green ball freezes every enemy for 3 s. Gremlins revert cubes as they climb; land on one from above to knock it off.

Discs ride you straight to the summit. Hop off the pyramid's edge and it's over.

Modes: Campaign is 32 rounds with a checkpoint every 8. Endless loops forever, ever faster. Daily is 8 seeded rounds, one attempt. Time Attack is one round against the clock, with unlimited lives.
