I did notice the armour giving health! What I meant is you should also get health from other upgrades, even if less than with the armour. Just to keep the gameflow for a bit longer:)
Ohhhh I see. We had a funny idea where you could find a mechanic who wandered around and could do repairs, but we didnt quite have the time to implement it. Thank you for the feedback though. I also think that'd be super fun :D
