Played for about 20 minutes, and I don't think there's much more to do. The long intro and long prologue make up most of that playtime. I beat the "boss armor bee" and there doesn't seem to be anything else to do. There isn't even any other combat other than the "boss fight" and you're extremely overpowered for that fight so I don't think combat is really implemented yet. The 0.2 version number is pretty accurate.
Also the tags and description are wrong, this is a female protagonist game. There isn't even anyone else living in her house. Description makes this sound like a slice of life type game similar to imouto or Summer Memories and this is just standard RPGM fare. Maybe that's what the dev has planned, but currently the plot is "female heroine tasked with killing an evil demon planning to destroy the world" (EDIT: OP updated tags and fixed description)
There's a few typical scenes so far, I don't think sex is implemented yet, the only scenes I saw were mild harassment--pretty standard for what you'd expect in the beginnings of an RPGM game. No nudity that I saw other than undressing her at home.
There's also no run option, so I hope the dev sorts that out because walking everywhere at slow speed in RPGM games is bad news. Translation is also weird, feels like MTL. Lots of names without capitalization and item pickups are missing their names upon interaction (when you pick something up it just says +1). Inventory displays item names correctly though.
Thanks for the upload
