Reviewing Public Version: [v1.6.8]
This game is good in general form, it has an intriguing history, characters and world building, the fetish list are applied very well, so if you are into it or just wanna try like myself, go right into it. The artstyle is not the best thing in the world, but at least it has its consistent. As for a RPG game content... simplicity it's the best word to describe it, you can't buy a single weapon/armor/acessory for the entire game (Or i was dumb enough to not see a weapon/armor store, since many doors you can't simply not enter for any reason), however there is a item store with basic stuff to buy, making it only place that will make your money worth of something (besides story plot related stuff).
These two factors will generate two things one "good" and the other is "bad". (the quotes are because the factors can give different opinions based on your own experience, I will point out what I saw this generating in my gameplay).
The "good" one:
Almost no grinding is required to beat the main story.
The "bad" one:
A low difficulty (maybe a hard mode should fix this).
After complete the main story there is optional maze dugeon for story reasons, and i dunno if you gain anything from it, cause i dropped it after 1 hour of frustation, so i personally can't recomend playing it, but feel free to try yourself.
