Fantastic “game of mini-games”! The art direction is wonderful and the palette is so well integrated you would not even think there was a “limit” on the number of colours you had to use for this game!
The mini-game mechanics share some similarities with the ones in my game but yours are way more nuanced and the presentation is very well done.
The only critique I would have is that the instructions for “Melting Metal” is rather difficult to read due to the “white text on light background” issue.
