Good job! The art style, the music and the theme are incredibly consistent, I loved all of them!
Also the main mechanics is intriguing and made me want to discover what incredible combinations I could do... until I discovered there was a complete schema of all of them :P
I encountered some problems with the stats, as they were not updating when I removed items from the six client slots. That made the experimenting a bit difficult, and I had to start over a bunch of times to reset the stats.
However, I can say I really enjoyed the final result, and maybe with a bit of polishing that could be a fantastic game!
