[Update 1]
It's a first build review so there's not much to say just yet, just leavin that here so you know what to expect.
-Attention given to the UI (got his own phone ui in place of your regular rpgm menu)
- Renders are good, aesthetically speaking but also in their quality. I mean, it's not your average shitty 3D renders that rpgm is used to. It's not pixelated or weirdly posed.
-Story is a bit plain so far(well it's only 30~60min). Seems like standard NTR corruption.
-there's a system of relation point between MC and the gurl, much like training games like princess/witch trainer, in the sense where you can speak, spend time and gift things to them. Not really clear to what end it goes so far.
To sum it up, it's a very solid proof of concept. If you're into NTR stuff, you should definitely keep an eye on it at least.
