Has anyone ever considered/done a btt for this game? It's been done for other switch/wii u games and I'm just curious. I mean even a 1.0.0 community sum of bests would be more than 25 minutes faster than wr (~1:56:04).

There are individual leaderboards for each floor and if someone really wanted too they could just splice those all together with some load/text segments from actual runs. To answer your question, no I don’t think there ever has been a BTT for this game.
