I found that this game has the same inherent flaw that plagues many “get rich” games in that you’re just clicking around to make a number bigger. However, this isn’t a huge problem as some people like that kind of game, so it didn’t affect your score. You could try to resolve this using mutual exclusivity or synergistic interactions that synergize one thing more than another if you plan to update it.
However you nailed the theme perfectly! Everything did in fact feel like a resource. Easy 5 stars.
Another gameplay wish is that clicking the button to get rid of a material instead sold it, with pitiful values being applied to non-crafted items.
Nothing to say about the visuals and sound that hasn’t already been said.
Well done!
