With attractive pixel-art design, an entertaining narrative, and largely compelling gameplay, Aegis Defenders is mostly a winner. Unfortunately, the guesswork and lack of flexibility in tower implementation keeps it from being an unqualified success, though. The developers have made a valiant effort at combining genres here, but as good as their platforming is, they didn’t think the tower defense through as well as they needed to, leaving Aegis Defenders a game that gets within striking distance of greatness without ever managing to hit it.
