Pretty unique concept! I found the final boss fight to be a bit of a struggle though, it was very easy to get pinned to one side and then you just have to accept your fate haha!
Nice idea with stealing speed / jump from enemies though, it would be cool to have a variety of enemies with different stats to steal!
I had a fun time playing this one through to the end and could see the idea brought to life in a more complete way in the future!
Good work!
