I dont know how gameguardian works because I never got it to work but it looks very similar to cheatcih3. I found an easy way to cheat in Toy Defender.
You have to modify the skills cost. You have to search skills that have not been upgraded yet to find the letter that changes all skills price. When you find it, I believe the letter is d: then change price to zero while on the skill you want, upgrade, change value to 0 again and then upgrade again, do this for every skill you want to upgrade. I will show pictures of unpurchased skills that are not unlocked yet, the letter is different but it shows how it works.
If you have any questions, write me on facebook.
