1UP: I consider myself to be a fairly good Portal player. I finished both the first and second games in less time than what most people consider to be 'average,' and I've never had to resort to an FAQ for help. That doesn't mean I never got stuck; more than a few times, I didn't have any idea of how to proceed. This invariably leads to me getting frustrated, a.k.a. shoot the portal gun wildly in the hopes that it will suddenly work on a surface that it didn't when shot the previous 402 times.
