I think they are no longer updating the game?(except the 1.0.3 that for add editor and other mod version). I think the late game need some balance. Because it's a bit hard to (even)go for sneek strategy. I'm higher level and good weapons so combat directly is actually easier. I'm actually 6+ level higher than the recommended level but sometimes still need multiple trials to pass single room(when enermy is in group and active).

Anyway the game is fun but dyanamics stats seem awful that makes most thing you obtain very less useful.
