This was great! I was really pleasantly surprised by how big this was, and how much fighting there was. The time travel hook was such a good way to extend the maps - I liked the cave map recycling by blocking off certain corridors.
There were a couple of times when I started to wonder if it was too long. I tried to sneak through the tower without tracking down the Cyclops and just got myself a second run of the dungeon T_T I liked especially the final-final dungeon which reminded me a lot of the World of Darkness and the Interdimensional Rift. Extremely cool use of the maps there.
I think the throughline of the humour was really vital to the whole thing too. Little bits like seeing 'Burly Boy' as Minos's job kept me chuckling the whole way through.
I never found the significance of the wistful girl's comment "I should never have gotten out of the way of that snail", did I miss that or is it an outside reference?
