This game-demo is a good quality but the movement of the breasts needs to be juggled a little more freely and Alma should have some moaning to it.
I would really suggest that there should more sex positions than just pussy teasing and fucking while standing. It should have like blowjobs and anal. If this is on the real thing then I am more satisfied.
Your loop music sounds good for it moves from slow teasing to real fucking. I like that but it should added a little more like a Saxophone and/or guitar perhaps.
My verdict is 3.5/5! It is a good quality game and I dig with the art because it is very identical with the Vixine Comcs but this game should have added a liiiittle bit more to it. If my suggestions we're on the real game, then I am downright sold maybe a 4.9 or 5! Cheers to your work. :)
