It's good, it opens. However I'm not sure how and when I'm supposed to save. I reached the third side but I died so I'll be starting over. It doesn't bother me but when I try to save, pressing enter when I'm in the slots, it doesn't work.
There is also this problem in the settings when you access them from the main menu, press esc to close them and it will glitch the game, asking for it to be closed.
Even with those points, I really like the game! It's so cute!
