Very nice. Graphics are good, and the story interesting. Characters are fun, and the little tidbits are amusing. The music is simple, but doesn't get old, and the sound effects work well.
As others have mentioned, the load times seem a bit long, and the right click option isn't ideal for many of us. Personally, I use a laptop scroll pad, so mouse aiming is a pain at best.
In all, looks like a solid game start.
