Lab Rat Not a bad try, but unoriginal
There are too many of these types of toons out there (the "stick figure in some sort of maze of death" type toons), so unfortunately, I can't rate you much on originality. I chuckled once or twice, but for the most part... Not too entertaining, sorry. Certainly not worth blamming, though, it's not bad for a first submission.
The "step" sound is really irritating, just because it's really loud and repetitive. A very soft thud or click would be more appropriate, and even better, have several different sounds to alternate.
The big spike ball thing was really predictable - I would have loved it if the guy had dodged it somehow.
