Hi. I'm a total noob to game making myself.
I really like the way it looks. I think you did a great job of making it look retro. Maybe you should make the controls clear on the game it's self, as it's not clear unless reading this thread. I think I would have prefered pressing r to select rock, and pressing p to select paper and pressing s to select scissors.
Is that the frame rate displayed in the top corner? Isn't that a bit fast? I thought games were supposed to be like 60 frames per second. It took quite a while to load, and it used up a lot of my processing power. As I say I'm new to this so for all I know it's ok to have frame rate that fast.
Thanks!

Well, I thought about using letters to select rock, paper and scissors but then I realised: what about random? xD So I decided to use A-D instead.
And about the fps... there are two ways :1- Fixed time step(fixed about 60fps) and 2-Variable time step (depending on how fast your computer is)
Take a look at this thread it might help you:
