Pretty cool game! Instructions are simple, and once you get started it's pretty catchy. Progressive and challenging too, though, feels like the mana button isn't very useful at first - you regenerate as quickly as you collect the mana, and since you can't shoot while you collect, waiting is almost as efficient as collecting. Well, maybe it gains uses in latter levels, but that's just my first impression. Graphics; sound; gameplay all good! Nice work.
