I'm not much of a puzzle player, but this was really good. The artstyle is immediately compelling and, in my opinion, more pleasant to look at than a lot of the other abstract games I've seen. The only downside I encountered was that the lines flickered very heavily, despite playing on a high resolution monitor on the "high" graphical preset. Honestly, based on the clarity of vision and design, I don't think it would have too far to go to be a commercially viable game, if that's something that you're interested in.
