Linking an Epic Games account is required to play online, nowhere was this mentioned on the steam page.

This game must have been the most fustrating games i played, but only the first hours. Once i got used to that dying is a part of learning and i got better, the game got much more fun and ejoyable. Having the traits system really made the countless runs throught the randomly generated castle feel fresh.
The skill system made me feel stronger from either getting smaller boosts in health, or getting new abilities for classes like the headlamp on the miner which lets you see every treasure and secret in the castle.
This game is a must for people who like rogue like games and fun as hell platforming.
