Nice little platformer! Art and music were really nice, would be lovely to see it polished up with some more sound effects.

Little feedback on the art-side: In some levels, the second especially, it's occasionally difficult to see the cat against the background because some of the trees themselves are quite dark. Having those a bit brighter would massively improve visibility, alternatively you could put a fog like gradient over the background to give it a sense of distance and helping the main character stand out more.

Me at the start "oh what a cute cat :D"
Me at the end "poor kitty :'( " 
Lovely platformer I enjoyed it.
