Pleassssee, can anyone help me. I've been stuck on this puzzle for like 1 hour, it talking about sum switch things and needs a key card (I've already done the switch part [2,4,5,8] but I can't find the key card)
Go back and on the other side (In the room before this one, take the left) you'll find the key card, and the gallery is exclusive to Patreon members :)
