Unlike what the other guy said, Z/X is not opening the in-game preferences menu for me, and enter isn't opening it either. I don't know what might be wrong.
Hi, most likely you tried to open a save file that was created in a previous version. I have identified the issue preventing the menu from opening when that's the case.
It's caused by the menu not finding any reference to the preferences that should have been initialized but isn't when loading an old save before it existed.
I'll add a patch for that on next hotfix. In the meantime, you can either create a new save file, or modify your current one. If you want to modify it, hop onto our discord and poke me. I'll help you repair it.
