Confetti Cannon perk
makes all weapons and drones shoot confetti
in addition the charge engine sprays confetti when you use it
and when your mech explodes it turns into confetti
When someone builds their base, if they don't know how many of each building they will be able to put in, the symmetry may be messed up later on. Also, it would be more convenient if we could put all the gold mines right next to each other. So I suggest adding the ability to move the buildings around, possibly for a small gold fee.
