Ehhh, my playthrough as a rogue showed how much unbalanced the lava level is, atleast there is no way a rogue can skip it without spawning with the goblet at its side. The towers can spot you very easily and there is no way you can avoid the eel's damage since even casting evade they don't forget about you. And i thought Ice cave was hard, hahah stupid me.
Hmm, nice game, nice mechanics and full of surprises, that kind of game where knowledge is power, the way i finished it was warrior on ice cave was so funny, since there was so many ice statues to slow me and i got overwhelmed by monsters that i wouldn't defeat cuz it would take an eternity, i kept using charge on the statues to get to the goblet faster without needing to bother with monsters. Also i found a bug where i can't move my character and i can't quit and save. Here is a screenshot http://prntscr.com/etla88 atleast i wasn't at a far stage of the game in this rogue run. 5/5 maggots have never been so scary.
