thank you for your help.
If I simply change the colour of Shrek from green to red and change the name of the game from …Shrek to Shrekh…Would this be helpful and help me to not get sued?
I am not the copyright owner, I am only sharing what I know about how others may have worked around issues of copyrighted characters. As it stands right now though, you are intentionally violating copyright and trying to profit off of it. That can result in a harsher response from the copyright owner if they decide to take legal action. I suggest you update the page as soon as you can, or take it down in the meantime.
