Hey dev, this is a good update! Still I think about the luck factor, you don't need to change it (because this is RPS, we can't help it :P). My suggestion is to show a hint to the player on what the enemy will do, but it's not every turn. The hint have a lower percentage than half to appear, so that it can be a little challenging.
But this is also fun, because I can beat the enemy easily now and it's really satisfying :D
Have a good day and happy game dev!
