The game looks really good but I would never write a 21 page story... Usually to come up with games I make a simple prototype that is fun and playable. Have you started doing anything else except the story? You seem to have went into a lot of detail for a game that doesn't exist yet.

I tried both engines out and personally I prefer Unity 3D.

The lack of rendering to texture and dynamic shadows in Unity Indie are not that limiting. You could still make a game that looks great, or try to develop an art-style that doesn't require dynamic shadows to look good. As for Unity vs. UDK, UDK seems to be more geared to develop shooters with high quality graphics and Unity is more of a blank slate that lets you do anything. Sure you can get the same results with UDK but unless you are trying to make an FPS, allot of code will have to be rewritten. I also heard that the built in networking in UDK only scales up to 64 players where as the built in networking in Unity is not limited by a number of players.

Overall, Unity is much more user friendly and it's cross platform support makes it very easy to run your game anywhere. UDK is more of a professional level tool with fancy graphics rendering and an FPS code base right out-of-the-box.

Depends on the variety you have in each level. If they're all the same with different patterns then 30 - 40 levels should be fine. After that it would start to get repetitive. If you plan on introducing new game mechanics every few levels that would help in making the game feel less repetitive. It really depends on your game but I hope that helps.
