I had to download firefox for this one and I'd say it was worth it. The physics and the art were very polished. Some bugs with the right click for rotating not always working but that's a minor complaint. I think there was a lot of missed potential here though. If there were different coloured dominos that did different things that would have made the game more complex and enjoyable. Most of the levels didn't require much thought but instead precision. That was annoying because sometimes I felt like the camera angle was working against me. I assume if you had a couple more days of time the game could have been really great. Maybe you could keep working on this.
