Everything, from the game's basic mechanics to using the system's time and day, to modifying and moving the game window by itself.
What does not
Only a potential crash during the Mettaton EX fight, which happened only once.
What was not tested
The first half of the Genocide route, and anything joystick related.
A native Linux version of the game is also available for sale on GOG.com, which was uploaded only one day after it went live on steam. This also shows the commitment of Toby Fox to the GOG.com platform.
