Really awesome demo!
A few suggestions, but maybe I just missed it:
1) More descriptions. Had to figure some things out like giving milk to goblins & the level of the milk.
2) Choose which goblins are in the nest. Ended up losing most of my basic goblins, but had a lot of shaman(?) goblins & I wanted as many basic for my front line.
3.) Pleasure rooms need to be more worth it. Currently breeding rooms & pleasure rooms both give 3g, but pleasure rooms are way more expensive.
Anyways, it is an amazing demo & I look forward to seeing where it goes!
