There's obviously quite some effort put into this. For what it tries to achieve I believe it's pretty solid work. I do believe the abilities need a bit more of fine-tuning (the bounce more specifically, I think you can gain height a bit too easily still), as it stands currently, it's a very powerful character but still able to give fun to speed demons, though I wouldn't want to go against Poyo in Race or any Match-derived gamemode.
As for the abilities, yeah they have been done before, but honestly? I don't mind at all. All I can really say is that you've done a very good job programming them in, and as long as something is functional and not too janky, I do believe there is merit there to be acknowledged.
I'm giving 3 stars because I'm a little biased against recolors (though I know how difficult spriting is. I couldn't do characters from scratch if my life depended on it), otherwise this would've have been easily a 4 star.
I'm eager to see what you'll put out in the future! Keep up the good work.
