How can I place the research lab for the aliens and how can I build the alien oil pump building? I tried to spam alien slime on the ground on oil resources but I still wasnt able to place that building.

Btw. Awesome work! Maybe one day we get even more type of aliens so it is really fun to play as alien vs humans :)

I also noticed that when I tried to place it but I found out later that the hitbox is way bigger than the building sprite. Try making lots of room where no other structure is in the way. Also, you have to have slime under the oil to build an oil pump.
