Lots of destructible obstacles added, including icecubes and bubbles, which can contain foes!

More patterns. Last screenshot’s the most interesting: Foes with breakable parts and projectiles!

Currently programming attack patterns for non-boss foes, and I’ll probably be doing this for two whole weeks. But I’m having a lot of fun with it, so that’s good.

Added some new bullet behaviors that didn’t exist in BH1, such as bullets orbiting around other bullets, and I think the patterns are looking a lot more interesting so far.
