Thanks so much for this feedback
Glad that you like some of the new features!
Some thoughts on the negatives:
Rules disappearing: This shouldn't happen and sounds like a bug. It happens again, can you email us the steps to make it happen again? We want to fix this!
Creativity: In some ways, would images expand your creativity? Like if you can draw or create something in Paper or Assembly or with color pencils, and then include it in your project? For example, in Hopscotch, all the icons you see are drawn by @Rodrigo. We code them into Hopscotch.
Cost: Hm, depends! Is Hopscotch different than games like CandyCrush? What do you get out of it? I think it's more than just a game — it's a tool for making things and learning. Also, it's about the same price as other apps like Club Penguin and Tynker.
