I'm going by the preview pic that shows a "long pipe-thingy" mapping. I've seen games done in RPGM that rivaled Renpy for game presentation so I know it can be done. I just don't enjoy spending half the game trying to get somewhere.
I get where you come from, but for me it's a bit differently. I like RPGmaker in general, there are good Games created with the tool, however such Games often are Timeconsuming, and i'd like to argue most of the folks who play Porn-Games are here for the Fap(which is also a reason why i don't play "normal" erotic / porn visual novel for fapping, because they focus more in story, character|dialoges and so on, and only have very few eroitic material or sex scenes. For me it often is more a part of the atmosphere or make the progression for the lovestory more natural but anyway) so to run around for alot of time until you get the scenes is kinda frustrating. With Renpy Games sure there are also examples where alot of things is written, but atleast you can skip on that if you want and you have a pretty natural flow so yeah.
The Second Issue for me is that alot of this RPG Maker Games don't use the strenght of the Engine. Sandbox-Games as example works better with RPGM than with Renpy, and that's when i enjoy RPGM if i have more freedom... but even more linear Games work, however if it's like some of this "run straight from one person to next person to trigger events), so no kind of puzzles or whatever, only dumb running around(i think sarah story or sarah adventure (or whatever i can'T remember well) was one of these).... ugh why...
well anyway i will give this a try.
