UK indies Mediatonic sure are a busy bunch. Not only did they release a ton of browser games for the likes of Adult Swim and SEGA, as well as mobile games, but their previous PSP Minis title Monsters (Probably) Stole My Princess was pretty well received earlier this year. And that one even made Xbox Live Indie Games for a cheaper price in August! Talk about having a diversified strategy, eh?

Their new game Who's That Flying?! is a PSP Minis shoot 'em up with tower defense elements that is up for download today! But how well does Mediatonic handle the shoot 'em up genre? And what the hell does "tower defense elements" mean anyway?
