Thx for this super nice game.
I found 2 bugs :
* On Linux, at the end of the second level I clicked "Exit" instead of "return to the menu". When I launched again it said "go to the mountains" but only the 2nd level was available.
* When clicking "undo" during a fire spreading, some fire stop, some continue and even some depolluted soil replaced the ashes in some cases.
Anyway, many thanks for the game.
