Gentle Player
Arcane
I hated crystal caves so much more than lost izalith. Just in case you were forgetting that this is just a dumb video game, let's remove all correlation between what you see and the collision geometry of the level.
Prism Stones, which are cheap as chips, and you're sorted. Crystal Caves was child's play compared to the second dungeon level of King's Field 1, which had invisible pathways spanning lethal drops but no Prism Stones, no tell-tale particles dropping down on the path and no developer "Path Here" nor potential player-written Soapstone messages.
