Arcane
To be fair, almost all dungeons are small with a short nearest way to the exit. Afaik there are only three longish ones - the Portmeyron Castle, the Lost City nad the Tomb. In the first one you don't have the beacon yet, Lost City is laced with various exits and you're not meant to pop out from the Tomb before you're done there.
But to get to exit, you have to go through several unnecessarily long load screens. And you can't even switch to browser - damn game stops level loading when window is not active.
