What works

Played chapter 2 from start to finish (pacifist route)

What does not

There was only one issue in my playthrough:

Seizure warning! (and minor spoiler warning for the seizure warning)

There are a few puzzles in the game which caused graphical glitches for me. The whole screen turns black, though the sound keeps playing. Maximizing the window (via window manager) causes the game to flicker: one frame is black, next frame you can see the game, and so on. As soon as you solve the puzzle, the glitch goes away.

These puzzles come in 2 adjacent rooms, right after you and your team gets kidnapped by the Queen.

This glitch does not happen in Windows. I don't know if there's a workaround.
