Fun game, really nice for killing time & gets rather addictive when heading for the next upgrade. My only complaint would be the amount of ads, but also completely understandable in a free game. I hope you'd be willing to buff the amount of resources received when selecting to view an ad at upgrade stations/forge/plank machines though as they're rather low integers at late game. - Keep up the good work & I hope you have more updates soon as I've already maxed out all my current equipment!
