This was intended to be practice, but there's no required order, so I just turned it into a run without LiveSplit. Here's the level times:

• Champ II: 2:22.23
• Spiral: 2:11.10
• Manhattan: 2:17.11
• Dungeon: 2:01.73
• Highway: 2:34.93
• Junction: 2:37.38
• Champ I: 2:29.76
• Half: 3:48.36
• Total: 20:22.60
