Stolen sprites, poorly imitated gameplay. If you're gonna use the SMW sprites, make a game that plays like SMW. 1/5, would be 3/5 with new decent artwork and sounds.
Derivative, adds nothing new to the genre. Very little decision making, too few differences between turrets. Only one map?! Good concept with the moving avatar turret, but overall mediocre presentation.
Really needs the eyestrain issue fixed... If the site doesn't allow fullscreen, up the size and legibility of your text, don't just scale down hi-res text.
