Nice looking puzzle Game, but I am not sure if I really understand how it works ... Anywas It has a good look and feel.
I made a Video playing your Game
hey!
yes that could help, or a kind of tutorial where you visualize what happens under the hood step by step ... pick a card, move it towards yellow wait hapf a second, move it towards red, and so on...
and to be honest I am not the type of guy who reads descriptions,... maybe that would have helped too ;)
all in all it is very nice looking and a promising game concept, could become something big. keep it up!
