I think it's a great game. I think its made more for mobile more than pc (which is what I tested the game on). Everything feels nice to play. You used the theme very well for the game. There were sometimes where the game would drop the same colour four or five times in a row, which afterwards a different colour would be dropped which I wasn't ready for since I was used to the other colour that had been dropped 4 or 5 times in a row(usually green). Overall, I think this is a great little game that implemented the theme very well.
Thanks for checking my game.
