Thank you a lot for the feedback! I'll definitely be adding an "undo" key when I get around to creating a more complete version of the game.
There are actually 2 secret endings and one true ending, with 7 total true loves. Keep an eye on the main menu as you find them ;)
If someone manages to find all true loves I'd be really impressed! Perhaps I'll leave a hint after a week or so...
Thank you for playing!
