Entertaining enough to bring me back for more after playing it for a few minutes late last night... But far from perfect. With better balance, fewer and more well thought out towers, more levels, persistent achievements, etc., it could become a 5/5 - I hope there is a sequel that does these things. 4/5 for now, probably should be 3/5 but +1 seems fair for getting me to come back a second time, which is rare for Flash games.
Cool game, just wish it was longer/harder. I hope we get a sequel. 5/5 despite length, since it's very professionally done and quite simply a blast to play.
