Looks neat and simple to go. Jelly!
I feel like a short example of the difficulty rate is needed, just for the GM to be clear of what difficulty set for particular checks. E.g., easy, normal, etc.
Thanks so much for checking it out and giving feedback! I uploaded a new version that has a difficulty table. Admittedly, I couldn't really test if they hold up, but I run them through AnyDice real quick and they generally seem to work.
I also added some more options for handing out tokens during the game.
