Thanks, Mooncake. I always wonder when I'll strike upon the idea that can actually be fleshed out into a project that's fun for longer than 15-30 minutes. Maybe this could be it.
As it stands, the weapons change automatically when they run out of ammo, represented by the blue bar middle-bottom of the screen. You can increase their damage, range, and firing speed by holding Q if you have enough scrap gear, those little sprockets the robots drop. I put the scrap in kilograms to fit with the theme hehe, but it displays as
what you have kg / out of / what you need kg
I hope that clears it up! Thanks for playing.
