I added a co2 tank ,––I added a pipe for sending oxygen to the carbon burner, ––I made materials only show up after you obtain them and also did some debugging.—————————————————————————————––I added a co2 tank aswell as a co2 gas sprite which shows the amount of co2 in the tank.–––––––––––––––––––––––––––––––––––I added a pipe to feed oxygen to the carbon burner so you can actually burn the carbon to make co2———————————————————–I made materials only appear after you obtain them so it looks neater in early game and also kinda just has a discovery vibe—————————————————————————————I did some ‘debuging of bugs” caused by my new updates. one thing I couldn’t figure out yet is why the water storage and copper pipe cooling system didn’t speed up the lasers anymore, I guess i should work on that now. Until we meet again.
