The Pyramids demo is pretty lame, if simply because of the art style. It's just hard to get excited about Windows 95-looking games. There's something about the way it (doesn't) animate that makes the game feel like it plays worse than it actually does.
I know people rag about the pixel art "fad"; call me crazy but I think that when it is done well it can make this type of game a lot more enjoyable. Old school looks suit old school gameplay. And the limited animation would be less distracting.
