Hi miniwoolf! Super happy that you enjoyed Stickyfoot. Thanks so much for your kind words :)
I'm glad that you appreciated that all the levels are available right away. This was a touch that I wanted to include after my last game was a little on the rage-inducing side, so wanted Stickyfoot to be more accessible. Glad it was appreciated.
Haven't heard much feedback about the credits song until this comment, and it's one of my favorite things about the game! Really happy to hear that you enjoyed it :)
Thanks for playing!
