Never been a fan of prestige / ascension / rebirth myself. Much rather have passives that make me become powerful just to watch the money soar without me having to keep looping the same boring parts.
Didn't mean to be designing your game. I try to offer ideas and get that a lot from devs. I apologize if I come across as overstepping. I play a LOT of NSFW idle games and a lot of them have similar features such as the ones I mentioned, amongst others I did not. But for QoL I felt the max button would be essential, at least. Otherwise, the game becomes a clicker game without bonuses for clicks as I pound out 200+ ranks into a single concubine at one time at higher levels lol
I will say this though, for some reason, your game runs my laptop mad hot. Like the physical case gets hot to the touch even after a few short minutes of running it. Only your game seems to do that and I have no clue why, and persists even with the laptop closed and screen off, so it isn't tied to the graphics, I don't think.
Edit: scratch that. I ran some Windows updates and now it is running much cooler. Strange how high graphical VNs with animations didn't do it but yours was. Either way, it is fine now, so whatever, I guess lol
