Tunic is absolutely a game you should play yourself before watching someone else do it (think like Outer Wilds). Control is like 20 hours or something, not too long, I haven't played the DLCs but idk if a SGDQ run would include them. And yeah, try to play the Celeste DLC before its run too, it took me a very long time to get through but I'm not good at games lol.
Very slowly becoming a Final Fantasy aficionado.
