I don't think I'm the only one who hates installers. Though I can't fault you if this is a limitation of the engine. This is probably why you have so few ratings. If I can find out how to actually play it, I will update this comment.

Edit: So there isn't any gameplay or interactivity, but you did succeed in making a textless story. I would suggest making it more simple and slow, since there are a lot of things happening with no words to explain them. Essentially, you could have cut some things out.

*sigh* now to uninstall it...

Very god story telling, without the use of text. The art style very good, Very fun experience.  I would say it's more of a visual novel than a game, but it was still a lot of fun.
