After being stuck at certain levels for ages it occurs to me that you could perhaps implement a "way out" pass prize.
Stuck on the same level for 50 or more attempts is no joy (Been there...Got the tee-shirt etc etc. ) in fact it almost always leads to me stopping playing for days maybe even weeks on occasion because I simply cant face it, and that's not good, I love my fun.
So a "way out" pass prize could be something like Jane's puzzle or Austin's Riddles or The dog's Treasure Hunt in which you can earn a pass prize to use when ever you are really stuck and get you started on track again without having to sulk and "fall out with Gardenscapes for a fortnite.
