Star Dance! is an endless runner type game in which you play as a star traveling through space and crashing into other stars. you must rotate your star around a circle to "catch" other stars. the catch is that depending on the color of your star and the stars coming at you, they can either: make you faster, make you bigger or destroy you entirely.
you start off as a random colored star that is either, red, blue or green. and then your color changes to the last star you destroy.
now if for example you start off as green then you can safely crash into other green stars, which will slowly make your star grow, which adds a multiplier to your score, but in turn makes the game harder because you have more chance of hitting the wrong color.
if you hit a blue star you will destroy it and your speed will slowly get quicker and you get a point bonus
if you hit a red star then you are destroyed. again simple enough.
but this is only if you are a green star, once you hit a star (except your opposite) you will change to that color, then the rules change to accommodate which color you are.
if you are green then you can destroy blue, if you are blue then you can destroy red, if you are red then you can destroy green. attached is a handy guide!
thats pretty much it, you get points for how long you can manage to stay alive and how much points you get!
