Final level, finally! Sure took a while to reach that last level! The medals don't feel very balanced that way, with the huge gap between all and the last two, but the gameplay itself is as balanced as it can get. Great variation in enemies and scores, though the pop-over notices for extra ammo/score are a bit in the way if you finish a wave late, and the next one is right after. Also, seems the more I play this, the more it starts lagging. But a browser restart and it's OK again, seems like maybe a little memory leak there? Anyway, game itself: love it. It's arcade gaming as it's best, challenging but rewarding; not difficult to get into or keep going with. Good game.
