I know that later in the game 30 gold will seem like nothing, but it's kind of sad that at the beginning of the game it's more rewarding to do mindless, repetitive tasks like this that only require a single mouse click, than to actually play the game. It seems like it's just an endless pile of wood that I can keep clicking on forever, getting money by doing nothing.
I think it should be 3-6 gold each time you chop wood, not 30. That's just ridiculous.
