i was keeping an eye on this one for a few months, but decided to finally play it.
renders are good quality, not the best but they are good. i wish they we just more of them, i dont know how much images dev has per update but they are definitely not as many as the big guys. of course they make anything from 5k to 40k a month. this guy currently has less than 700$ a month. and its not too bad but i just noticed it.
the story is good aswell, its pretty different from your usual "MC corrupts every girl with his 30cm magical dick" altough this happens here too, its done differently, kinda more natural and realistic (as much as it can be for a "porn game) characters are not brainless bimbos, craving dick because they saw it, they have peronalities and are well written (not acting lessons good, but still good) i get twists of my life vibe from the plot. the sis seems to be attracted to MC from day one altough not showing it immediatly, you can see it. it gets bonus points from being different from the other games where character goes from hating the MC to loving him in 20 secs flat. the pacing can be kinda "off" i dont know how to describe it, but again its not a big deal.
what i like most about it is that the choices matter, and they dont punnish you for choosing whatever you want. the game will have something to show you depending on YOUR choices. BUT its not THAT choice heavy and it is fairly linear at times. the main plot (i guess it is) cant really be changed (at least until now i think) just reactions and dialogue will be different.
havent followed the dev and this thread, so i dont know how often and how much content he has per update but for the game i rate it 4/5 def worth playing.
