I like the game and its concept. Played it couple of hours and got the same bottleneck as everyone else - the stones. The ratio is around 1:3. For every stone comes 3 logs. And thats the main issue. Thats why the stones get blocked by the logs so often. Maybe you can kinda build a different biome, where stones are more common than the trees. So they get even at some point again. Plus, when the third type of trees appear, the stones are still the same and no different version. Also you may add some damage to the fire, because otherwise there is no real reason to it in my opinion. Dealing 21 damage to trees and only 1 damage per tick from the fire seems outnumbered by the normal hits themselves. 
Just some suggestions you might think about :3 '

Keep up the great work!
