At present it is designed more as a puzzle, there is a "More Optimum" way to play, at some point I will be adding some weighting on the opponent's desisions. It isn't nessisary at this time though, your rock paper scissors comparison is correct as the design was partially influenced by me wanting to see how I could add meaningful choice to a rock paper scissors like game :)
--- In this case because the options are weighted differently there is meaningful choice, as opposed to in rock paper scissors the percentage chance of any given move working is exactly equal as it is a perfect triangle :)
So in short I will be adding greater choice to the opposing player but it will be as a result of the current "puzzle like" system as opposed to it having a preference for doing something specific. --- Hopefully this all makes sense :D
