Excellent game and puzzle complexity. It definitely can be an app with more puzzle. I put it in my top 3 best game of the Jam! Only proposal is to make the green Gem move a bit less on the vertical so that we are sure of the square they are on.
Thank you very much! I definitely do consider to expand this one out! I thought of adding little shadows under the gems to make it easier to deduce where they are, but ran out of time :)
