I'm not talking about point and click minigames for RPGM, rather the ones like jumping and pushing puzzles, and triggering switches that are made in the engine itself. It's designed for certain types of puzzles like that. Some minigames can be fun even in renpy and unity games, but the ones in IW tend to just be annoying with little in way of payoff for completing them.
What was I trying to point out was, the puzzles minigames (like the pipemania type, 'drinking game' choice type, matching panties, inside IW i.e) are prevalent in old school point-and-click adventure games, and that is the genre IW is following.
Those are "point-and-click minigames" as the input is mainly the mouse exclusively, and were present in point-and-click adventure games, like the Monkey Island series, Larry, and many many others, etc...
What I understood that you said before, was that you disliked the IW minigames and those were better suited to an RPGM game (which they aren't as the minigames are mouse type mostly, and RPGM is mainly keyboard/controller which is suited for those jumping and pushing puzzles that rely on character control you gave as an example).
The payoff bit I totally understand though. Despite unlocking progression (is kinda... meh), I think they should be a more rewarding, even if they don't reward with anything related to the main girls directly.
