RGBlock

Swap colours on the beat to run, bounce and climb through ruins at dusk.

RG Block is a colour-swap runner. A little block runs and jumps through a ruined world on its own. You choose its colour: red, green or blue. Coloured floors, walls, water and gates only work when your colour matches. With the wrong colour you drop straight through or bounce off. Grey takes any colour. Every colour change lands on the beat of the music. Swap just before contact for a Perfect: each Perfect adds a layer to the song, five in a row bring in the full band and double your coins, and ten triple them. Miss, and the music fades back. There are 21 short levels in five chapters. Each one adds a new idea: bounce pads, water, paint, updrafts, lifts, slides and slingshot rings. Finish all five chapters to unlock Endless mode, which gets faster every stage until you fall. Spend your coins on 12 cosmetic skins. You can play in portrait or landscape, with touch, mouse or keyboard.
