Wow, thank you so much! This seriously means a lot to read.
I spent a lot of time trying to make the balance feel challenging without being unfair, so I'm happy it was appreciated. The color-clearing was a big thing I hoped would give people that "one more run" feeling.
And yeah, the tutorial took quite a bit of development time, but I felt like the game really needed it. There were enough unusual mechanics going on that I didn't want players to bounce off before the fun parts clicked.
My wife deserves all the credit for the art style too, so she'll be happy to read this. Thanks so much for playing!
