Oh damn it's been a long time! Finally getting back into retrogaming, let's see if I can still do this...
Sinistar: 64,655
Using a keyboard, not a controller, so I can only go in 8 directions. Also got caught by Sinistar as the final sinibomb tracked down and hit him just before I got eaten. I don't think I lost a life for that.
Star Castle: 11,010
I might have time for improvement, but if not, at least I got these scores here. Excited to get back into the tournament!
