Show HN: Annulus. Like 2048 but corner strategy won't work and you can win donuts

This is our first game. We obviously came up with idea while playing and loving 2048 but wanted to build something that is a little bit more difficult. Annulus is different as any time two circles merge, they change the color and hence putting similar circles in any corner strategy won't work.
