The levels could've been made into a pack in the "rotssctf01, rotssctf02..." -sense, for easier reviewing, but little does that matter.
Also, Dodges' level's filename was listed wrong.

As for what I think:

1. Tube-Tastic!
2. Betacarotene
3. Sucky Level
4. Hypercube
5. Drought

Gorda deserves an honorary mention as the 2nd-best looking entry, peace.
