Eh so all the setup didn't amount to much
"Asuna, why did you let him fuck you ?" "Well, he asked very nicely."
"… Asuna I like your fingers so much , I would love to have one on my key chain. Could I cut one off? Small one will be enough! Pwetty pleeease!!!"
Yea putting it simply dev couldn’t follow with the original vision he had. It really shows in later parts and second game doesn’t have the switch anymore.
This game is narrative driven still, most of the time you are reading. Also VN can be about seeing as much as RPGM are.
Combat could be replaced easily enough (since here the combat purpose not to provide gameplay element but to showcase the combat groping) honestly I find it strange there is no renpy port. It would take me 1/5th of time to complete it if the game was in renpy, RPGM are exceptional at wasting your time with those transitions.
