Finding a kitty was hard! It took me quite a lot of time to understand that you are not in the same room all the time.
Strage things happened -- every second (or so) startup ended up in game freeze. It can be because of running .exe through wine though.
About the engine itself - it looks interesting, but it doesn't feel finished. It would be cool if buttons had their own font - it wasn't clear where you can click and where you can't. I would also like to be able to change font size.
Thank you for your game!
