Glad you had fun with the hold function! You're right, the game is not balanced for it and it makes things easier than intended - but if it makes it more fun, then go for it! I won't tell 🙊
I'm imagining the tutorial will be a few set downstacking scenarios, clear 5 lines with these pieces
Someone in the Turbo Fat Discord suggested I add some parts of the How To Play wiki to the downstacking tutorial, specifically the "Cursed Shapes" section: https://github.com/Poobslag/turbofat/wiki/how-to-play#cursed-shapes
