i liked the concept of this game, and there's a lot of complexities you'd have had to deal with to get this running.
I found the controls tricky. Perhaps a simple mouse click on a button would have been more interactive (and mobiles it would be tapping the screen).
Some audio assistance as well would be good.
I found the colour wheel and the colour block at the back not matching up, which confused me somewhat.
Well done though!

At first I had the element activation only during the phase where the colour's shown in the wheel (so in between it would go to a fifth "neutral" state) but this didn't work at all. Debugging showed me it would flip the colour and revert back to neutral immediately after. To solve this I kicked the "turn to neutral" bit out, so the colour stays active until the next one is registered...
