Finally! I've beaten it after beating my poor wrist with so much click & holding the mouse button. Was worth it, though. :P
I first tried the native Linux build, but it seems somewhat bugged/imbalanced. For one, the spawn rate of "pickaxe rocks" was extremely low and sometimes I could go more than one hour without getting one, while they did spawn pretty soon and abundantly when using the Windows build via Wine. Also, cutting down trees very rarely resulted in a "hut spawner" on Linux, while there were several of them in almost every tree cluster on Windows+Wine.
Anyway, and as many other have already said, this is an incredibly solid foundation for a bigger game. Please keep at it!
