Fixed replays of some very old plays which had stopped replaying properly on newer versions of the game.
Fixed a bug where the camera would sometimes glitch out when viewing a replay, when the original player used a save point.
Fixed a bug where, on some levels, the "revealing a secret area" effect would wrongly apply to a larger area than just the secret area being revealed.
The game will now "sleep" and stop burning CPU cycles when you're idle in the Level Pit menus.
Improved graphics for when a laser touches a silicon crystal.
