This is definitely an interesting take on the rock/paper/scissors game style which is enjoyable. The way the game works is fluid and I like the way the pentagram is used to make 'elements'. Albeit a little bit of a creative direction take on the use of the pentagram itself.
A little bit of criticism would be that it's a little predictable. I.e. it's rock/paper/scissors. Figure out the pattern, and whre there is none, try the one you think it right. Otherwise it's an enjoyable experience.
