LiveSplit does not support macOS nor Linux, both of which are officially supported by the game. I think it's a shame to automatically exclude a portion of the user base and i ask the mods to reconsider that rule. LiveSplit One does exist, however, it doesn't support autosplitting and global hotkeys are only supported on the desktop version, which seems to have some issues on Linux at least.

I completely forgot this game was released on macOS and Linux. Thank you for letting me know. I have updated the rules.
