I admit that some of the effects don't hold up that well. I still found this to be a good game. I am a fan of these sky shooting games. I appreciate how it goes at a pretty nice pace. It does come off as a tad too slow in that sense. The music is fairly good.
I was afraid that the upgrades were going to be pointless because I only had them for fifteen seconds, but I got more as quickly as I lost my old ones. I still wish they would stay. It seems to be a pretty ambitious game. There could probably be some more variety in what the enemies look like. It has a pretty triumphant tone to it.
