I am playing on a Mac, and when I play another Unity game after playing Direct Ascent, it opens in the same aspect ratio as direct ascent. This can be solved by deleting a file in ~/Users/USER_NAME/Library/Preferences/Unity, but I would prefer not to have to delete that file every time I want to play Hollow Knight.

[EDIT]: After testing, I have determined that this bug only affects older versions of Unity

Confirmed, priority is important.

I'm not sure if I'll be able to fix this one, as this is a Unity-based issue, but I'll see what I can do.

EDIT: As this bug is only a bug on older versions of Unity, so this bug will be marked as Won't Fix. This should only be an issue when you're doing something like playing old Ludum Dare games, as games should be updating their versions of Unity. If you are still experiencing this bug, do what FlashViper said and delete that file.
