Welp, I finished the game, and I've got to say it was amazing. Great writing, great voice acting, animation... everything. Can't wait for HL3.

Only bug I ran into was the not being able to jump and, related to that, there was something messed up with my collision detection. It would randomly fling me across the room after gently tapping objects in the level. It only did this in the "Dark Energy" part. I started a new game and started from that chapter and everything was fine. *shrug*

Anyway, uploading the rest of the screenshots now. I think I'll go through the game again slower this time.
