This was the most frustrating route that I've ever ran. Figured out that there are a couple spawns you can get in the room to the right of the first room you enter - Decided to build that into the route and try to aim to leave the first floor or building with 5 enemies remaining (sometimes would leave with 4 remaining, like in this run).
Excited to see someone beat this score. Would love to see how this route could be used, but also I think it's just cool that this is the shortest run in TH.
There are a lot of little quirks to this route, if anyone ever has any questions about it hmu I can probably help out.
IMO this map is the best to test out and experiment with AI behavior - I think it'll be the first one where we'll see some super optimized routes (ie, shooting in certain locations to bait certain pathing and things like that).
