Turns out that the fireball spitters on the level "Blockade" don't have a hitbox. I accidentally walked through them and wound up out of bounds. Whoops.
It would be nice to know the max amount of elements a factory can produce if it is under 100% efficient so I could know how much more I would need to upgrade it in order to upgrade it to where I wanted it to be. A simple "Produced/Max Produced" would be really simple and helpful.
ok it will be added in the next version!
