3 problems with runtime

Game Engine Game Engine Support and Discussion
1

Hi, everyone!
I made the lowres game character and want to use Blender Game Engine for character demonstration.
Character have proper UVs, material with 3 textures (color, normals, specular) and simple cyclic turntable animation. When i press P-key and run Game Engine everything looks fine . But when i go File->Save runtime ive met few troubles:

  1. Large size of exe-file. Probably because of high-res textures and their format. I like that all textures a included to exe-file. Any solution for reducing exe-file size, exept converting all textures to jpegs?
  2. A lot of dll-files that are needed for aplication launch. Maybe some of them isnt so needed for my demonstration? If this true, how to turn they off? Any method to include all dll`s right in to a exe-file?
  3. A normal-map does not work. Just doesnt work. What the problem?
    Help me pleeease =)

1- remove all unused data from the .blend
2- no, you cant (atleast not without manually recompiling blender)
3- check if its properly packed
