I ended up finding a ROM dump of the game to try out, I'm glad I did because I was getting curious enough to buy it. But yikes, it's next to unplayable. Choppiness in sprite animation detail aside, character movement is sloppy, jumping is floaty (even if you short hop), and there's a weird charge-up button mechanic that seems like a terrible idea for gaining super meter. Why would you have super meter that requires you to NOT attack or be attacked in a fighting game?? "hold on, let me stand here and charge my abilities".
The character sprites are too small on the screen, makes it feel too zoomed out for a fighting game, and their designs suffer from the sprites having to be so small.
$19.97 is still too much to occupy space on my shelf.
