Very good, but way too short.
The stick figures weren't too stick-figury, if that makes sense, to make the rating lower because they are sticks, and the animation was very fluid. I thought some of the death scenes were giggle-worthy, and the fight scene at the end was very funny, but not laugh-worthy, more like a smile. The background music isn't loud enough to be noticed, and if it was noticed, when I turned the volume up, it was very forgettable and generic, but again not really enough to lower the rating. The only reason I found a nag in is that it's just way too short. If it were longer and full of all sorts of creative stick deaths, it would have been much, much funnier and five-worthy. For now, it's very good and worth a 4/5 slash 8/10. It's a good filler for more content to come, though.
