This is pretty good.... I think Yu walk a tad too slow for my taste tho..... The Art is really cute and the writing isn't bad, it's no masterclass in flowery descriptions but it's pretty good, helps fill in the blanks for the sex scenes. The scenes are pretty nice but could use more art maybe like cumshots with Mona and Xav.... And the Breeding worms had no art tied to them at all sadly....
I'm gonna chalk most of that up to being an imcomplete Demo. (I only played it in browser as of this comment) I imagine that with more art in the sex scenes and more inhabitants to interact with you've got a good base for something pretty sweet. Good Job :)
