The game worked fine for me - I'm using Chrome on Windows 10. I love the different options despite the simple mechanism, and the graphics and music are beautiful as well.
There are just some typos here and there (e.g. "Congratulation", "beautifull"), and there seems to be a bug where the endings I had acheved do not get counted. For example, the game told me I had only 1 ending left to find, but when I finished the last ending, it suddenly told me I had 2 more endings to do. Some endings I found did not get displayed in the menu either.
Good game, though!
