I'll be giving patreon build alpha0.43 to the 3$ tier since there's still only one piece of exclusive content available, the Machine Gun Weapon Arms.
I'm going to be working on adding more content fit for $7 tier and up.
My next development focus is on adding the other leg types to mech customization:
Reverse-Joints
Quad Legs
Tank
As well as adding more stats to the mech builds to make different builds feel even more distinct.
