I absolutely loved the character design. Very silly looking, and the upper society feel of them is just so funny. I didn't think I would enjoy it as much as I did, but there's definitely something in it that make you want to continue and complete the level.
A minor complaint is the changing dimensions with space - I think I'm so used to jumping with space, I kept falling to my death.
That aside, great job!
Edit: I forgot to mention the sound design - loved it! I felt like the little dude was just walking away on those pipes.
