I don't know if you'll be adding anything more to this game since you're working on the sequel, but I found a couple minor bugs.
1. Leanne says you have 5/5 outfits unlocked regardless of how many you actually have unlocked for her
2. Katelyn says that you have 4/5 outfits unlocked before you actually unlock the 4th outfit, and once you do unlock the 4th outfit, it then says you have 5/5 unlocked even though you only have 4.
3. I don't know if this counts as a bug, but a lot of the later girls have their scenes that show off their 4th and 5th outfits happen before you actually unlock the outfits. Like, if I remember correctly, they play the 4th outfit's scene at lvl 75 when it unlocks to wear at lvl 100.
4. Some of Erika's first scenes display her original outfit instead of the appropriate one for the scene, if I remember correctly.
Also, I really feel like, at some point, it would definitely be worth coming back to this and just cleaning up some of the loose ends, like some girls (main & summoned) not having the personality section of their bios, and some of the summoned girls not having their dialogues. Doesn't need to be soon, especially if your time is taken up by work on Spiral Clicker 2, but it would really improve the experience if there weren't so many obvious signs of "incompleteness"
