1. the overall loot quality is worse. in t2, there are more green chests, but the boss room felt exactly the same as t1. the entry fee is fine, but the rewards in this room specifically need to be buffed. the locked chest rooms could also use a loot buff. i think the overall quality in t1 is perfect, t2 needs more though.

2. it is difficult to coordinate to get enough souls to trigger the boss. there needs to be some kind of way to share souls

3. the crawlers are buggy. im gonna be honest i liked the spiders better, but i understand how they didnt fit, thematically. their hitboxes are inconsistent imo and it's a chore to get through them

4. t2 doesn't really offer much of an xp boost either.
