And the spider’s theme is… webs and strings, obviously!
I’m actually having a lot of trouble beating this guy, and there’s two more bosses after him.
I’ll have to practice more!

The hovertank’s theme is “following you around and trying to hit you with it’s massive canon”.
I didn’t have to think very hard to come up with that one.

Anyway, a lot of the patterns’ difficulty depends on how well you manipulate the tank’s position.

I updated the design for the hovertank boss because I wasn’t satisfied with the original one. Plus I think this one will suit the factory levels better, since they’re gonna be quite gray. It looks pretty damn cool in motion!
I also started playing around with filters in Starling. A 16-bit mode is something I’ve always wanted to add to my games, and it turns out I can do it with just one line of code. Hurray!

Here’s the source for the filter, btw.

In motion you can tell it’s a filter, but it still looks pretty good. In screenshots it looks almost legit. It doesn’t seem to have a huge effect on performance (or at least not on my computer), so I’ll leave it in as a bonus feature.

I think this is my favorite boss so far. The way she(?) moves around ended up looking pretty cool. Her theme is fast movement and honeycomb shields!

Adding in the honeycombs makes me see how much better the game will look once I draw proper backgrounds. Oh, and the honeycombs are there to punish you for spraying bullets, and they change up the gameplay quite a bit. I might actually go back and add some bubbles to the turtle boss.

The Protector’s theme is… maze-like patterns!
His walking animation is also programmed kind of cool. The animation’s speed depends on how fast he’s moving, and can even be reversed.

Also, HFX posted a preview of the first boss theme: http://www.newgrounds.com/audio/listen/586743
