Well, I never expected this to be someone's kink, but here we are. In that aspect, I think the concept pretty much lived up to what it was trying to do and showcases that off.
Like others have said, I can see that a lot of care has been put into the animation. I do feel, if you're keen in exploring such an exotic kink, that there could be a lot to add-in that could improve it as a term of making it more game. Right now, it pretty much just draging the worms in from a side and seeing them developed, with the particles in the end as reward. Maybe you can add some different type of worm mix-matching? Different types of characters that react differently? I feel there's a lot that could be explored to take this beyond hyper-alpha.
Best of luck for what you plan to do with this game next. Cheers! 🐳
