I didn't expect this to be an idle game because the intro implied some sort of adventure.
Cute chiptune music, clean looking ui and nice parallax (is that the right word for that?) clouds on the background.I also enjoyed seeing those little goblins running across the screen to pick up fruit and go mining and all that. A downloadable version would have been nice because I can't have it running on the background while I'm writing this review.
One minor nitpick - some scenes in the intro cuts off too quickly, and the main theme doesn't seem to loop properly.
