Incredibly well done game. Really engaging, appropriate difficulty, lovely theme.
I feel like it could have been a bit more directed, like I wasn't really sure what I was trying to do. Of course that could be a design decision as well because it did add to the mysticism of it all.
I also found the coloured circles a bit hard to connect to the resource. I eventual equated the colour to the resource but perhaps an icon or even the lovely art on the card could go in the little circle to make it easier to parse.
There's a bug where you click on the card multiple times and keep getting the reward for every click.
Very well polished, lovely animations, great card art. Just a lovely game all around.
