Version 2.1 change log:
• World 11 (has 10 levels + 2 bosses)
• Intermission scenes in Endless
• New earlygame levels + enemies
• Completely new menus that are way cooler
• General polishing and touch-ups
There's some really minor stuff like the database entries that weren't finished in time, but I really just wanted to get this main content out there after 6 months of working on it! It's a pretty big upgrade over the last release.
