Hi Klink! Welcome to the Forums
Thanks for donating a map to the Junk Trunk, it's about time somebody made another stand alone Boss level, hehe. Great map by the way, I finished it in just under 5 minutes with 215 Health and 5 Missiles remaining. (I didn't realise I had any :p) Excellent indeed for your first level, I can't wait to see what else you come up with
The only glitch I noticed was that the Finish Zone wasn't actually a Finish Zone. After checking in the editor I spotted the reason, the trigger at the end of the level should be named Race Goal rather then Race Finish.
This is very similar to a map a friend of mine made, (is still making) though not as evil as his. <_< his has 5,000 HP on the shield if I'm not mistaken, and I think 5,000 on the main body as well. (and what makes it so ridiculously hard is that the main body is a super sized Guardian, so he keeps flying into you. And the fact that there's a ring of invincible triple turrets attached to him. I'll try and persuade him to give it to the Junk Trunk, hehe!
