I think I broke the power system. My florinol battery that's supposed to bootstrap into better stuff has been modified with lava to be self-recharging, enough that I can run the laser non-stop at T6. Biggest challenge I faced building this was hauling enough lava up from the reservoir.

Tried to take a recording of going wild with the laser, but Sandustry isn't playing nice with my Steam overlay.

It's a fun little game, if a little short on late game content at the moment.
