I agree totally, midway through making this i realized it would be an impossible compile whilst maintaining decent fps and fast-paced gameplay, so i essentially abandoned it.
Finally i compromised on haphazardly throwing together what elements i had just to appease the kiddies at hl2world. Oh well, you get what you get - its not perfect, but I felt bad wasting the theme, maybe someone else will be inspired to make a better one? Ah well, take it at face value.
