Hi, it's me again :p
V0.13 Functionality
The functionality where you can choose what to feed the newborn from update 0.13 is not very confusing when you have a few new born, but when you have a lot of newborns the latter can be complicated to maintain. I think it would be practical to add this functionality to the room where the newborn is located.
Market/Colony
It would also be nice to be able to sell certain units at a market or exchange them for slaves to another goblin colony.
Camp
After the defeat of the humans it would be good for the board/terrain to change to a place with more light (instead of rock there are more trees or something else like destoyed house), like the goblins are moving and we make the fallen kingdom their new home or make the fallen kingdom their second camp allowing them to pass from one land to another
Other Idea
I still have a lot of other ideas but I think you must already be busy with bug fixing and implementing future features so I'm not going to ask you too much
