Hey so i thought of a way that maybe you could help me without confusing me, i wanted you to tell me what to do from the entrance of the ruins without being to specific, you dont have to do this if you dont want to but i would help a lot, and what i mean with not being to specific is like "Go up, down, (etc)" all you need to do is tell me in which room i should go etc, remember you dont have to do this if you dont want to or dont have the time but honestly without help i will be stuck there for a while, if you help i would appreciate it.
yo i felt a bit stuck too, but i figured out that you can move some stones on the ground by pressing z (or enter) and move toward the black trail on the soil, if you try that on every possible stone block, you should be able to find a way out
though don't be afraid of getting lost in the ruins, eventually the path will appear by itself :)
have a problem: the difficulty to beat the ruin's 'boss', is it really high and you need to farm for a long time monsters to xp, or is there a feature that i don't understand in fights, am i too dumb to beat it...?
basically what unUnder said. as long as you see there's black trails on the floors where there are barrels/boxes try moving them to where the black trails lead new pathways can be found that way as well. I can't really rmb which room exactly but from the entrance of the ruin, turn left and don't head to the place where there's red blue green icons on the floor. eventually after moving some barrels around you'll find a room where it only leads to a door and this door will lead you to the rock thingy that will give you access to the thief. ofc needa get the rusty keys too but sorry i can't rmb the locations for the keys
