This is really well done!
The theme of a knight climbing a tower like out of a storybook was charming and the border art, the cover picture, and the music all support the theme well. The climbing mechanics are well implemented and you feel like a physical thing climbing the tower and having to look around for hand holds. I didn't reach the top and fell a long way to my death and my guy sounded like he said "uh-oh" which is like, yeah buddy you just broke all your bones! That's a big uh-oh!
