Thanks for the feedback!
The earlygame is still in a tricky place since this is a type of game that starts clicking when you have multiple options to kill things. Only having a sword/bow and opening a door only to get clown-car enemies flooding out can get a bit overwhelming. I still gotta figure that part out.
As for the level up heal, I consider it to be one of those clever player-abusable mechanics. As another dev put it, you could know you're close to level up and decide not to heal, in order to maximize efficiency knowing you'll get healed soon anyway. This requires a more obvious EXP visual (instead of having to check the stats page), but I think the core concept is there.
Its unfortunate that the game bugged out on you when it did. I'll take a look and see if I can figure out what happened.
Thanks again for playing and the review! It's very appreciated
Edit: I wasn't able to replicate your staircase bug - if you have the time I'd be thankful if you would copy the log file it autogenerated after playing. It's -should- be in C:/Users/Yourname/Appdata/LocalLow/osur/Tower Of Kalemonvo v.15. The log itself is named Player.log. Well, you probably know this since I see one for World of Mold right next to it on my PC
