It took a little to get the hang of it. I think my problem was the difference between left and right attacks was much harder to see after stealing the sword. So waiting till the last second to steal the sword definitely helped.
Really liked the game over screen changing over time, very nice touch. I think a tutorial or at least walking the player through their first pickpocket would've really helped me understand what to do. And of course, simple attack and pickpocket SFX would greatly improve the experience so consider adding some if you plan on updating this.
Great job executing on such a unique concept!
