Thanks for your opinion! Now there is a way, or even couple of ways, to progress with NO stats improved. There are items hidden everywhere and some of them are locked behind skill checks, but it's perfectly fine to achieve first planned ending and hidden ending without extra skills. Only the true ending demands you to improve couple of skills to serious level and those extra stats can be earned through consecutive plays and puzzle solving.
I'm a little torn about this, as it's not stated directly, so people can be confused by it, but at the same time I want to have a layer of mystery and feeling lost, a type of game that makes you wonder what could be done with different skills and items.
I think that next iteration will be combat-focused though. I'm trying to make a game that is available for all types of players. In current build you still can fight with monsters but these weapons are hidden behind some of the nastiest hurdles.
