If you find yourself short of wood to finish this level this guide is for you. There's only one important thing to have in mind here: DON'T COLLECT the wood that's lying around. You start the level with 99 units of it available. Whatever you collect without spending first goes over the cap and is irreversibly lost.
So start the level, collect food and work on obstacles. Deal with a few pits and then start picking up wood piles - not earlier.

Finish the rest of the level as usual. That's it! Hope this miniguide helped you a bit - if it did please rate it ;)
