Hey - thanks for the feedback - much appreciated.
There was a pause function, but I hadn't realised I seem to have switched it off while working on other bits, will re-instate this ability with the next build - thanks for picking this up!
I'm focussing on the editor / camera at the moment as this seems to be the area most folk give feedback on. I'll add in controls (like Q and E) for height adjustment of course. There's also a camera movement smoothness issue when the structures are larger which I've been looking into.
Just for future reference there are some help documents within the game, if you click the green question mark at the top left of the screen it will toggle help text relating to wherever you are - so if in the editor it will list editor commands etc.
I could look into the speed of the fire propagation as well. At the minute you can toggle between nothing flammable / some flammable / all flammable - but I could introduce a slider for speed of fire.
A downside to this is that challenge levels will look to see if all fire is out before deciding if the destruction is sufficient - so if the fire spreads very slowly you could be waiting a while before getting the outcome.
Once again, thank you very much for both taking the time to have a look and also providing feedback afterwards. I really appreciate it!
