game is 50:50 NTR to not NTR.
you toggle it in setting.
RPGM is trash. this game would be 10x better without it
I see this somewhat different than you.
1) The NTR-aspect isn't that easily described as you said. There are NTR-scenes for many different things and events, BUT: Many NTR-scenes get reused and recycled. They have the same animations for the same person. The vanilla ones with the MC get new animations and slightly different variations. Chyos said it was a ratio of 10:1. I just feels like there are more NTR-scenes, because they come from different events (but, as I said, use the same animations).
2) It's right, that often RPGM games feel like a huge waste-of-time and grinding. This is one of the only games, that has it's own graphics and is really well put together. So ASWS really delivers well with the engine. There is some grind, but it is used for creating an atmosphere. You often need to do some repetitive tasks, but you get new dialogs with the girls and you can feel progress. If you just play for the h-scenes, you won't get as much out of it.
And let's be honest, this game wouldn't work well with RenPy, because the graphics (and models) aren't the best as they come from VaM (Klub17).
