The artwork is definitely to my taste and match3 is not bad in terms of game play.

If you're looking for an opinion, one of the reasons I stayed with Aigis so long is that it didn't eat up a lot of my time. I could log in and burn though my energy allotment in a relatively short time (late game) if I was running late. The current roster on Nutaku tend to be massive (boring) time sinks.

Just wondering, what game engine are you going to use (assuming you're not building your own)?
