Thanks for giving it a go! Yeah the AI can be a little cheap-o sometimes, it's no substitute for a few real players. The "cascading" is one of my favorite parts of the game. I like the feeling I get when I'm playing someone, about to loose, then come back with just a few clicks. Pro-tip: You can also end the game in a tie which results in a rather interesting visual as the cube tries to figure out who the "winner" is.
Weird, not sure whats going on with the song playing after exiting, that's not happening on my end. We'll just call that a feature for now.
