This is a disaster of a "game".
Or "game". It's not really a game, more like a 3D movie with one or two gameplay elements (keep the circle within an area to avoid cumming).
The girl has to describe what happens visually (typical for many Japanese games), the girl's vagina is shorter than the head of a bottle (poking my uterus, it hurts)... and, the gman shoots flourescent cum which sticks even after a long time. So either the girls do not bathe, or they just love having cum on them for weeks or months.
But, in short, not a game. Not a very good 3D demo, either. It's like, the sources could be used for something, but that something is not a story where you cannot skip annoying speech.
I can see that it's early access, but they might as well ditch this and go a different direction. This is so fucking boring I feel like I'd rather get fucked by that bottle.
