UP2037603: I was extremely impressed with this game. You can tell that there's been a lot of work done on the models involved; that, combined with the shadwers and music, creates a brilliant atmosphere that accompanies the well built gameplay.
I did find that the rockets felt unnecessary to use although it's possible that I missed their purpose. The rail system, although well designed in how it loops around a large and varied map, did make it very easy to accidentally collide with obstacles if you weren't fast enough to move out of the way.
The reloading mechanic adds an interesting check on the player's capabilities rather than allowing limitless fire to clear your way through the map; it seems like a very sensible decision for difficulty.
