Nice to see this finished. Disappointing that the pregnancy counters didn't seem to amount to anything, aside from maybe? producing kids in a couple endings and a pregnant Mida in one ending?
Also feels like there was a missed opportunity when MC allows Mida to attempt to absorb Lust. First, Mida must both be living in the tower and have a corruption of 4 or higher to even take control of Lust and put her in the sex dungeon. Second there is one final corruption increase when you allow her to try to absorb Lust. There should have been another corruption check, where after that corruption increase, if Mida is not at or near the cap, she would fail to absorb Lust properly, and Lust takes control.
From there MC would have the choice of either forcefully separating them and going into one of the other more boring endings, or rolling with it and having sex with demon Mida body that has Lust in control. Then later there could be an option for an altered version of the Lux Aeterna (Corrupted) ending where it's Lust (?separated and back in her own body?) helping MC get all the girls in her own way, for all that entails, instead of Mida with Lust's powers.
Oh well. It is what it is, I guess.
