I don't ever take the recommended actions by pressing R. The game is a sandbox with no predetermined goal, so you kind of have to make your own fun.
In my opinion though, the game is way too easy by default, even with the difficulty turned up to max. It spams you with way too many easy sex scenes, and too many scenes in general, which is why I've made probably thousands of personal edits at this point to the game's scenes to try and slow the gameplay down and disable scenes I don't like.
The game is also full of bugs as you mentioned, and many of them have been around for a long time with no signs of ever being fixed. Unless you're willing to make your own edits and tailor the game to your own tastes, while also overlooking the many bugs, this game may not be for you.
