Sorry if this is too simple,but I tried hacking this game a while ago,and failed,code injection crashes the game,even code relocation.
The game is free:
http://sourceforge.net/projects/mines-perfect/
I can find values easily,but I cannot change them.
Any help is well appreciated.

| It appears to be packed with a UPX packer.

Thanks for pointing that out,I just unpacked it,and I am able to cheat now.
I still don't understand how upx prevents code relocation.
(I only use PEID to detect packed softwares,I have never used it for games)

Can you tell me mate how did you change the amount of flags? 
game unpacked but still crashes at code injection with any new/modified code (pure injection without any differences runs fine)
e.g mov [edx],5 = crash
originalcode: mineperf.exe+1A9F0 - mov [edx],eax

Sorry for taking time to reply,but the function that is next to the instruction that writes to the flags is checking [esp],the return address,so you'd better inject your code before that,also,the instruction accesses other junk,here is the code for flags:
