Great gameplay concepts with the different projectiles acting the way they do (the delayed are my personal favorite) along with Ability Absorbtion, (which i've always been a big fan of) and the nice system with the turrets dragging behind you which adds a lot of strategy to what could have been a simple shooter.
Don't know what it was though that just didn't click with me.... maybe the faeries :P - but still 5/5 for great innovation!
