In-game timer (IGT) pauses when all enemies on a screen have been defeated. As such Real Time has more optimizations to make for movement and screen positioning. In-game time is only obtainable to a player on a deathless run. TNWOA has built-in leaderboards and time attack for in-game time. These boards are split between consoles, but not region. Some of them are highly competitive.

The game has short load times between levels but I'm considering this insignificant enough to not be taken into account at this point. IGT is easily obtainable from any video and avoids load time issues.

Because of these features runs with either timing method are accepted but Real Time has priority over IGT if both were recorded.

Feel free to discuss if you think timing should be handled differently.
