i am frustrated there is no walkthrough.. just get 2 endings.. no matter how i hard i tried..

and the developer also don't bother to reply message

Haha, still working on "My Soldiers", and I'm trying to release the full game by the end of this year. So probably I won't have enough time for the walkthrough of the demo.  But hey, IceDevice did a very good job about the walkthrough! You may check it out.
