Lag made it nearly unplayable - 1.66 GHz processor
I don't know why, but this game's lag made it nearly impossible to play - I've got a fairly decent processor (I would think) so playing on lowest graphics possible with an increased priority would make a better gameplay... or so one would think. I still got crippling lag, which made me waste ammunition and not aim as fast as I usually would have. I'd say a good idea for next time is to try to focus on code optimization, and make sure that ALL modern-ish computers can play the game comfortably. (I'd shoot for ~1 GHz+.)
Other than that, I found myself constantly trying to carry more and more stuff than I could handle, upping my strength every chance I could get. I think a bit more balancing couldn't hurt...
