Hi!
I'm one of the Devs who worked on this Game! I made all of the art you see, along with most of the animation. It was a blast working on this project and seeing your love for this game, months and months after we released it still puts a smile to my face. I read every comment and watch every video ya'll release :)
I'm writing here to let you know that a speed running page exists since there's so many of you speedsters

Keep on Caving and Keep on Busting
Thanks for Playing :)
