I really love this game and the direction the development is going. However, I wonder if there could be an easy way to add a little polish to the graphics. The tilesets include a lot of straight edges and redesigning everything propably isn't worth the trouble, but maybe we could use some anti-aliasing (or similar) filters to soften the rough edges? For example, I like the fact that you can see the amount of lightning for every square separately, but I wonder if the transition from one square could be a bit smoother.
This is really just about polishing, but if adding a few graphical tricks like this isn't too difficult, I think it would really add to the value of this game.
