You need to leave a bubble the way it was... I got to the big boss, but then i lost all my armor. So I every time I go back, he starts fresh. If you're going to renew the boss every time you leave the bubble, why don't you keep the bubble blobs after you use them once? It seems impossible for me since i lost all my armor...
Ok, I found out what the little numbrs mean, and I've found that the shotgun takes care of the strafing problem. After playing for a good while, I think there should be more zombie variety, a step in between the zombies and the devils would be nice. Don't give them randged attacks, just make them more durable. A campaign mode would be nice. I'm looking forward to the next installment.
I dont like how your limited to the number of ways to hit a star. I could try as hard as I could, but it would just fly back to the closest side of the star i was trying to hit
