A small suggestion, can you add flOre is Lava mechanic too?
I made a modification for myself locally, it was kinda easy even if I never worked with lua. Just copied flOre_is_lava function to control.lua and modified it a bit to fix global mod settings. Considering it would be the only script in the mod, it's optional, and it runs only every 120 ticks I doubt it would affect UPS in any significant way.
I played and completed dangOreous game a while ago, started another game with your mod and without damage from ore it just wasn't the same for me. Dealing with biters is a bit different from normal games when you can't run to nests and kill them and I like it.
Overall, thank you for great mod! I can't just return to dangOreous after it, I like a lot how the building is prevented instead of destroying entities, it was very annoying in original.
//edit: also, option to spill container contents when they are destroyed )
