Volt

You are a little battery bot running through a neon corridor. Tap anywhere and gravity flips - you snap from the floor to the ceiling and back. Red spikes grow out of one surface at a time, so the whole game is picking the right side and committing to it.

The nice part is that the gold coins always sit in the safe lane, so chasing coins keeps you alive. Coins buy crates that unlock 12 bots, and XP from your runs opens three more worlds after the Grid: Neon, Lava and Ice.

It speeds up steadily, so runs end because you got greedy, not because it cheated. Controls: tap, click or press space to flip.
