The visuals are crazy good! I really like the core concept and I think the audio design is great. I also like the foundation that was set up for the game. The title screen and intro were really fleshed out too.
My main critique would be that the character was a little hard for me to control. Because he is so fast, I would jump places that I did not want to go. I also think the black cat sprite was a little hard to see in contrast to some of the backgrounds.
Great work !!
