i installed the cheat, but now i feel it made it too easy specially for a new play .. is there a way to uninstall it or undo/revert the changes ?
Not automatically, no. This cheat, like most cheats, modifies the original game code to do certain things. To undo the game changes, you'd need to extract the original game. As for undo the changes like game stats, no cheat automatically reverts changes made to the save game. That's literally not how save files work.
It should be noted that this cheat just adds interfaces to modify values. If you don't use them, the game plays exactly like the original. I.E. this cheat only activates when you activate it. In other words, it only cheats as much as you use it. If it's too easy with it, but not without, it's only because *you* used it so much that it made it too easy.
With great power comes great responsibility.
