Sibling rivalry

The game can be played in co-op, with one player controlling Toodee and the other Topdee. But with puzzles designed around moving one character and then the other, you’ll essentially be taking turns at the controls – a slightly formalised version of the way the Gutholtz brothers played through singleplayer games such as Celeste on a shared TV in their old apartment, “where one of us watches while the other one is playing, and then one of us rage quits and the other one takes over”. There are settings to decide whether only the active player can switch perspective, handing over to their partner, or whether both players can wrest control at any time, an option Gutholtz describes as “chaotic”. But then what game isn’t, when played with a sibling?
