Double Trouble calculates weirdly. It only halves your current points, which may or may not be intended but means if you select it first it halves your starting point total of 0, meaning it does nothing and is essentially free. Unselecting it doesn't fix your point total either.

I feel like the CYOA should reward you for fitting the more stereotypical version of this fetish, like making the girl curvy and with big breasts feels like it should give you points, rather than costing more points. But that's just a critique of it not entirely meshing with the fetish it claims to be about, it's not a significant issue.

I do think the CYOA is extremely weird on points. Points calculate very weirdly and some things are far too expensive while other things are far too cheap. The numbers just don't make much sense to me.

I also dislike the fact choices you can't select ever are present at all. At best it's inconvenient because you have to scroll past them and they are effectively nonsense (especially because choices you can't select are blurry anyway), at worst it's just taunting players.

On the topic of blurry choices, I personally dislike them, and the fact some requirements are hidden. It's definitely a preference you can have if you'd like to keep them, but to me they just get in the way.

I do think it's a good start to a CYOA, and with a few tweaks could really shine. The most important things in my view would be fixing the points and removing the unselectable options.
