TL;DR: Simply awesome.
I have never seen a system this free before. Character creation is a matter of seconds, combat system is easy to learn, easy to master. No need to learn complex systems for damage dealing. Even mages are easy to handle (although I think they are incredibly nerfed).
Even if you are a hardcore player of another system, this definitely worths a try. As there is no world associated with this system, you can freely use your imagination (OK, that may be a con, if you are a beginner). Just go, create, and play within the hour.
