Imo the improved "combat sex" animations were worth it, most of 111 game's were getting stale
I'm a huge fan of ONEONE1's Work thus far, but I do kinda wish they were willing to try and experiment more with their games instead of falling into a very similar formula for most of them
Firstly, the whole "Three Protagonists" mechanic for this game was a fairly interesting and well executed one in my opinion, both Momo and Kinako had nearly just as if not more scenes combined than most HRPGs tend to have all around, but at the same time there was a clear bias for Mukuro which meant the other two got a bit shafted when it came to their own scenes, SPECIALLY Mei
I really want them to revisit and refine this concept more in one of their future projects, it's a real shame they don't plan on bringing it back for The Eclipse Witch
Secondly, I really want to have some variety with their characters and the ammount of scenes they get, ONEONE1 MCs are always Big Chested High School Age Girls, I really want there to be a game where we could get an older, more mature lady as the lead, like Aizawa for this game and Aletta for TEC
Thirdly, better refined Ecchi Combat, more specifically, I find the way ONEONE1 has handled battle animations and clothing damage to be very clunky and a tad underwhelming all things considered, I really wish they could make a game that put more depth into it, like The Moral Sword of Asagi
Sorry for the long post, but TL;DR ONEONE1 and their team put a lot of work into their games and are undoubtly some of the highest quality HRPGs out there, but there is room for improvement I want to see them taking with their future games
