Not bad for a second level, but could be better. And yes, I do wonder how sewers get frozen over so much in Wonderland...
GRADINGS
Puzzle 18/25 The puzzles were fun and hard enough, but they weren't very original. Try to spend more time on your puzzle. yot yot, (another user here,) told me once in a PM that he plans all his puzzles on paper before making them in the editor.
Action 22/25 Good job with the spikeyballs and the chomper at the end.
Storyline N/A I would recommend you start putting a storyline of some sort in your adventures. It's not the most important thing in a level, but you can only get so far with the type of levels you're making right now. Storyline adds purpose to the level and allows plot twists.
Scenery 21/25 Not bad, but this didn't look that much like a sewer.
Glitch-Free: 23/25 Was the chomper in the powder keg area supposed to kill itself?
OVERALL GRADE: 84/100

Good, but I still found some weak points.
This was better than your #1, but you should start focusing on a plot and some new puzzle ideas. Also, it's okay to make your levels longer. There are some levels here that are over 30 wlvs in size!

Not really around much these years.
