Very large saves load much much faster, without freezing the game.
Items can no longer get stuck under shelves, ones already stuck are teleported to the lab upon loading.
Removed font character randomization on the secret door codes, as it was causing 1's and 7's to look similar for some players.
Snake controls should be more responsive.
Fixed stutter that could build up while the game was minimized.
Fixed a few rare cases of the game spamming errors every frame, which could cause stutter.
