MDRG is a grab bag. The main focus is actually the interactive sex scene part, which you can stream for cash or just do, with poses unlocking as you buy more robot parts. Then it has Stonks mode where you can channel your pink wojak to make real money, nice because if you buy low and sell high starting with say $10K and repeat you skip the money & stat raising grind that makes Teaching Feeling bog down after a while. There are a few VN-style events, mostly funny or trying to be, and the headpat simulator which is optional except for one scene where if your robo like you, you do headpats instead of sex for about a week and she'll take matters into her own hands.

Yeah, it definitely isn't a highlight but the dev grinds hard to get the best H-scenes he can out of it. That and he just grinds period, adding a book-style chapter pretty much every month for the past 3 years, better than even some of the JP Ci-en guys.

Same here, I'm tempted. If you haven't, you should try Klaroro, which is like the Megaman or Alien Soldier to Repure Aria's Castlevania, where you blast and dick down the Seven Monstergirl Masters. No stages, just boss fights, but it's good.
