I had 500 ammo at the 21th tier, and got only 2 explosion bonus. At this stage of the map _I_ can not defeat the boss, I've tried different tactics and running patterns, but the best I got was 1 shot away from the star's death like 3 or 4 times.
I think the boss became a bit too hard, I got it down to say 1 health, then squashed me. I've started with 300 bullets, and had a lot lucky powerup drop. Problem with the powerups that hey are way too random. sometimes I got only speed powerup from 18-> tier 21, and like 2-3 within 5 sec, and nothing for the rest of tier.
The previous way of the boss was better in my opinion, because if you were good//lucky you had the chance to get more and more points, but this way you are enough lucky or not.
To kill a boss: shoot it a lot times, you'll se that the gray part of it gets bigger (or the middle red part gets smaller). It is gonna die when the middle of it is full gray.

I have some trouble with copying at this game or site, I'm not sure, but this link must be the correct one.
Problems: Monsters are standing on you.
you can shoot only vertically and horizontally.
Make LVL up more intresting: players should get points to spend on health, damage, range, etc. I would like to shoot with my mouse. Keyboard controll for this game is not the most suitable I think.
I like the idea of game, but those spheres should fall a lot faster, and because of that we could balance it faster. I've died because my balance totally screwed after 2 heavy combo :(. If you have time try to make the music more continous. I always hear when it restarts
