I played my happy heart to the kitchen where it suddenly went error on me while i tried to weigh an ingredient. No saves so unfortunately I won't restart as I'm about to go sleep..
The puzzles were fun, I liked it didn't restrict itself to a room and the hints were not costly and actually helped. I liked the idea and got the humor of the cats and all.
Additionally when I clicked Main Menu, it sent me to a black screen. Not ideal..
Space as 'back out ' is not as intuitive as say right click for stepping back. Would be great if you added a right click for backing out option too :)
