- Escape function removed, SCP can no longer just leave if NOTHING is in
sight
- Instead, SCP now uses vents to move around. Time to weld those vents
- SCP now only considers humans as targets (and not all carbons, which
includes such nice things as slimes) and only registers their sight
- SCP should now longer chainsnap targets
- Messages to span
- Logs are now red, for maximal attention
- Other improvements
