So you could add the Hoverboard in once you unlock cerulium (for the colour blue) and use materials such as solarium,plutonium,etc to make it.You could fly through a planet swiftly but it costs some energy only when you are moving (you can change this) but it cannot fly up only, well, hover but you can jump with the board sticking to your feet while you are still able to attack(again costing energy).I think this would be good for other people that are in a high enough tier to make it but havn't found butterfly boost or any other flying tech yet.
I think this is great. maybe make it so you jump normally yet on your way down you glide slowly. make it a deployable vehicle. which you can store in your inventory.
Yea I was thinking about the gliding part but I also you could deploy it like a human mech as it would be a pain to activate sometimes if you have full inventory, I know it would be a pain for me and probably other people too.
