First mode was great, quiz and pro sucked: completely uncontrollable on my gaming laptop. Quiz mode: stars wouldn't turn, Pro: Pictures wouldn't complete the level.
Around wave 40 and beyond, the targeting goes awry, and seems to target the last enemy it sees. Sometimes I think it just targets a random enemy, though. First Level.
