I think I liked this one a little better than Sonic 3D Blast? The slow running speed along with the fact that you're not able to jump honestly work better for the isometric perspective, not to mention how nice it is that the things you need to collect don't wander off on their own. Probably its biggest sin is the confusing way the doors work; if you go through one and try to go back, you might not end up where you expect. Otherwise, it's just kinda disposable.
