- added ability to use Lara's underwater swimming physics from TR2+
- added ability to wade, similar to TR2+
- added Lara's exit-water-to-medium-height animation from TR2+
- added support for 60 FPS rendering
- added a pause screen
- added a choice whether to play NG or NG+ without having to play the entire game
- added Japanese mode (guns deal twice the damage, inspired by JP release of TR3); available for both NG and NG+

- `/speed {num}`
Retrieves or sets current game speed.
- `/fps`
- `/fps {num}`
Retrieves or sets current frames per second.
- `/set {option}`
- `/set {option} {value}`
Retrieves or assigns a new value to the given configuration option. Some options need a game re-launch to apply. The option names use `-` rather than `_`.
