Thank you so much for the kind words and thoughtful review!
I think I know what you mean by "sometimes the clouds didn't go where I wanted and I didn't know why". I think that happens when you intersect yourself and so if you started pushing the clouds with your head, they might get stuck to your tail accidentally.
Initially we thought this was part of the challenge, but it's not clear when that happens. I wonder if making it so that if it's already stuck to one part of your body it can't stick to another would help.
Thanks again!
