the shadows and the light are very good, but if u can make it downloadable because the browser version is a little laggy, and make the look by mouse not by clicking, that will be amazing...
Sure, I have popped up a Windows build! Hope that's fine, I can't do any other platforms ATM.
Mouse look still requires you to hold right mouse button, though! I think if I continue with this I would like to experiment with you clicking in the scene to interact.
