maybe so. wanna do a mod for that?
i mean that its gets more complicated is the main reason for me that i want to be able to build on multiple levels
i can see some of the problems tho, saving would need to be revamped(eg. NAME.Layer.ship) and you would need to have some type of 3d variable in order to hit stuff on a specific level of the enemy ship(which probably is the reason as to why he doesnt want to do that)
