Big fan of the way you used slick, it felt great to nail a drawing and watch things move perfectly! Took a bit to get used to, I was stuck on the 2nd level for a while, but I'm glad I stuck through it to see the other cool mechanics you added!
I'm glad you stuck with it! Level 2 was meant to teach you how much momentum can be conserved with the right shwoop. You're right though, its a little too hard. Maybe a dotted line showing the ideal shwoop would be helpful there.
