The makers of galaga would shed a tear
this is just a badass beautiful game. dodge, firepower, and time all work together and its NOT impossible, just really realllly hard at times (btw, lvl16 > final in difficulty D:) .
The reward idea really got me as a good performance in one level earns you more lives for a tougher one later (or screws you if you sucked :P), an extra incetive to perfect your skills on earlier lvls.
Not to mention the bullets match the the techno songs perfectly it was often more of a dance then a bullet hell (the laser really blew me away, actually took a hit watching them fill the screen when the broke it down XP).
Faved, 5'd, and anxious for your next spawn of genius. we appreciate the fun!
