You're very welcome, and thank you for the kind words! :)
No cat girl in the game right now, but once Act Three progresses to the point where you're fighting Fey creatures, who knows? Maybe!
Financial support always helps, of course, but I never hold characters hostage until people pay me. If you can afford it, and you think CK is worth it, then I am humbled and flattered to receive support. But if not, I'll still try to fit in as many requests as I possibly can anyway :)
The game's story-focus means that just Shatter-blasting everyone you meet will never be possible, unfortunately. However, all one-shot girls (plus all Boss Girls) can be Shatter-blasted, as can numerous Side Girls and even one of the Main Girls if you choose to go that route.
