There are two bugs that i wasn't able to fix, the holding and releasing for the building is a bug it's not intentional, I think i did something wrong in the code I'm not sure. When clicking the menu button(X and O button) it is recommended to do it where you can't place any buildings such as water and built buildings.There was a delete building on the building menu but it would leave a black card instead of grass card so i didn't implement that, if you messed up then you have to restart or place building in a different location(unless you get unlucky with terrain generation and get the whole map water)
