The gameplay feels nice and the pieces look good. The light source might need some adjustments, some pieces on the right half of the board are sometimes a bit hard to identify.
Hah, I know that feeling. Possible fixes could've been turning down the reflectiveness of the coins, or, better: make them reflect certain colours. White, blue, red, yellow for the base ones and then mixed ones for the combinations. Only drawback is accessibility for colourblind people.
