I have a life value of 5 can not freeze , a Instruction access this and rewrites.

find what access and write and
  instruction that writes the "life" is
00456733 mov eax + game + 0f45, ecx


ECX = 00000005


I want to change ecx 999, but this Instruction modifies many other directions, the ecx changes at every step, and if I put a nop to the Instruction, the game corrupts and exits.

how freezing the ECX register to 00000999 when he writes to the direction of life?

Set a breakpoint on the instruction and find out what is specific about the opcode when it's affecting life.
It can be : previous return addresses of caller functions, pushed arguments, value in registers (other than ecx).
