Well, I just got through finishing this unbelievable game. I think its biggest strength is how it is so fricking addictive. My hands are the most tired they have been in a long time. I hope this wins Daily Feature and every other positive award in existance. By the time the boss came, it wasn't that difficult. Of course, I knew I still had to never let my guard down.
Everything is designed absolutely beautifully. It's nice to know how many monsters are left for you to destroy. There is always going to be a new and interesting design for a monster on the next level. My only complaint is when I'm stuck with that short laser thing. It does me no good at all. Luckily, I just play the level again and don't have it.
