TL;DR: Had truckloads of fun with this game when I was younger, might just get the Deluxe version on Steam because of it. Even though it's a bit of a hassle to try and play it nowadays with Flash support dying out online, there are still some workarounds. And it's definitely worth it to try, because the game's simple but effective combat and platforming is still stupidly fun all these years later. Controls are also snappy and quick to learn, and the graphics have aged surprisingly well. Too bad there isn't much to do playing singleplayer, aside from a very limited "campaign" mode, and challenging yourself against seven CPUs that are all teaming against you.

As with Super Mario 63, this is one of the better Flash games of its genre. Highly recommend experiencing it with an equally skilled friend.
