- Falling down / taking certain damage seems extra punishing because you lose all of your accumulated thorns.
- Thanks for making crystals never fall down the holes. :)
- Bonus for using all the plots in a stage? Or fewer plots in a stage? (Although I guess this is functionally similar to simply using the crystal seed...) Bonus for no checkpoint plots? If you want it to be subtle you could just alter the number of crystals in the next camp.
- If you fall down a hole during the button challenge, I feel like you may as well just end the challenge because there's zero chance of finishing.
