So I've played ~1h hour and most of it was looking for stealthy bonus scenes you need certain conditions to unlock. Gameplay is quite fun and controls are really nice (especially for typical indie japanese games) but there are 2 h-scenes *only*. And if your enemy is coated in pink "lewd" shader you get only second stage of this h-scene (finishing one). Merchant girl is only for "literally shaking" if you leave her without paying for items, which is quite funny.
So for proof-of-concept game it's looking nice but after 15 minutes there is absolutely nothing there. I've seen some placeholder values, like EXP or other stats that won't change no matter what you do, some inventory slots just for show. At current pace it could take whole years to fill game with decent content.
