Holy Blessed Cows!
There's this feeling you get after you finish a Weisi game, I call it the "Maus-Factor," where the world seems a lot slower and quieter because you just went from insane "Weisi-level" amounts of craziness to your regular life.
This game was amazing, and although it WAS crazy, for once, you could actually see what's going on more clearly, you seemed to have learned how to make everything go boom all at once, yet still make sense of it, a fine accomplishment indeed.
This game is a sequel as it should be, and to think you've made 4 powerfox's, each one better then the last, it's amazing.
I especially liked the genie, I found it an interesting mechanic, although you shouldn't have went with a "higher number is better" type balance, you should've made them equally powerful, but with the source of their power coming from different attributes (such as speed and amount of projectiles vs damage per projectile.)
Anyways, that's just my two cents, good show overall.
