It's a good concept to start off from but there is a massive problem with its execution. That problem being I could just keep clicking on one option and I'll still be more likely to win the entire game than lose (I did it 3 times with scissors and won each time). Also, the A.I. just kept drawing way too many times than if it were just randomly selected. I understand that maybe you wanted to include some balance that shifted better into the player's position but as it is, it's just too easy to win.

Test the game a lot to make it addicting for you and to fix up any exploits the user can have to beat it.  Also, try to extend beyond just rock paper scissors for the idea. There's another game in the jam called Rock Paper Scissors Roulette that also includes Rock Paper Scissors but brings in more depth so that the player focuses both on trying to guess right in rock paper scissors and the amount of bullets in the chamber and where. That could be a good source of inspiration to see how concepts can be expanded upon beyond a simple idea.

That out of the way, congrats on your game!
