What a cute and unique interpretation of the theme! A precision platformer where every jump you make costs a heart. The level and mechanic design compliments this concept to great execution, and I had fun playing to the last level. My only gripe is jumping against a wall slows the cat's jump, and took me a frustrating minute til I realised what was happening. I don't know if was an oversight or intentional, but I didn't think it was necessary.
I enjoyed this demo, well done!
