Variant is somehow a worse normal dungeon, due to being kept from doing big pulls, and you have to wait for RP walking npc, yapping the same dialouge every time.

12 different endings? more like fight the same miniboss 12 times, and each other boss 4 times each (one path you only fight the same boss 3 times yay). there is one unique hidden boss which is cool, but that's about it.
5 unique bosses, barely more than a normal dungeon. And no, the bosses having 1 new added abilitiy based on the choices you made, doesn't make it unique or new, its still the same fight 90% of the time

The puzzles are a joke aswell, and to call them puzzles is a insult to puzzles. Do you want to press the left or right buttom? so fun and exicting
