Is it somehow possible to keep the unlocked characters after you exit the game?
If you exit to the main menu you can save your game, or if you get a game over.
I feel super stupid but I can't find the option to save. I only see 'save and confirm' in the config but I don't think that's for game saves, only for saving settings.
The game features auto-saves!
Thanks. Something must have went wrong the first time I played it. Now it saves as it should.
