Great Work
Man, and I thought the first one was good. I appreciated the animated backgrounds. The sprites were also animated perfectly (although, I expected they would be :D). The remixed songs were a nice touch, as they were 'beefed up' and more hyper than the originals. They certainly fit the mood. The upgrade to 16-bit was a change for the better. The framerate was just as good as Bullet Bill 1, if not, better. Excellent job, man.
As soon as I finished reading your PM, I checked the portal. Sure enough, BB2. Under judgement and all. Now, maybe THIS will get you a weekly. It's about damn time >:D
