I'll just jot down the stuff here.

• Stormy Precinct Zone has mostly been redrawn. My friends and I have put in clouds, a river, and most colors have been darkened.

• HP system for Sonic has been changed to bloody rings to represent more of that other Sonic hack, plus, using just hearts is too generic at this level of improvement.

• HP system for the bosses was also redesigned, and you can now see the boss names at the bottom as well.

There's a lot more, but it won't be long for v0.2 to come out.
