Hi and thanks so much for commenting and giving feedback!
You can download a greatly improved build (v0.3) on the games main page in the description, i put a link there ;)
Stone can be gathered from the stone-piles for which you need two strong mice carrying wood to bump into each other and make fire. with two fire you can the build the stone-quarry. hope that makes more sense now!
But the getting stuck is still a problem we'll address next, aswell as some other things.
Thanks and Stay Safe!
