Thanks for giving it a try! Solving the riddles is not required to beat the game, though it makes it easier. I saw after the deadline that I had not made level 4 as easy as I thought. Other levels you can beat after failing the relic in the same run, but not level 4. The idea with level 4 was the NPC is standing on a weird thing, saying to do a thing, and eyes are pointing at a place. It could be really hard if the first act NPC dialogue is not interpreted as hints though.
