I think it needs some tweaks.

When you upgrade all 4 points, the ability to downgrade is removed which is kind of weird. I think it should also be accumulated in the point and skill area. Obviously I could spend 128 emeralds, but I'm not very rich :/

Why this name? Mad=Insane Cyborg=fits with the theme of advanced tech/robots Anyways this was inspired by the Creepers in Minecraft. Now this Cyborg doesn't really attack you, but it's very tanky (lot's of hp and defense) After some time let's say 25 seconds it'll explode !! It'll drop 2200 coins up...
