i totally agree with you, my main concern was not being able to maintain the lewd content in the hs1, like HUGE stretching with huge tits and ass, jiggle, mouth deformation for blowjob and kiss, nipple fucks and etc, my concert is at ease now, but the quality... damn that took a hit, i can live with hs1 but the quality had a downgrade, that CAN be worked, the models also need to be more faithful to the original ones imo, and the call me crazy, but as a huge tit lover i got some merits, there is a inconsistency on Karen tits, in some scenes(without them being interacted) the tits are sometimes huge, sometimes normal/big, imo they should be always huge by default
i'll keep having some hope on the dev as the game is maintaining it lewdness, i just hope that if the dev really go to this engine he polishes and upscales the renders, or if he comes back to the older engine this could be just an extra/bonus sequence, like the koikatsu one, and after that part we come back to the old engine for the rest of the game
