On Windows, pressing Alt + F4 will close your current window. So, any "cheats" that ask you to press Alt + F4 will not work, and if it's like this one: "new glitch! survive huge nest till 10 or less left,then press Alt+f4 instant all rewards unlocked!!!" then you will not even get a high score, if you earned one!
However, if you read this and still press Alt + F4 because the comments told you so, please follow these directions EXACTLY:
1: Find a brick
2: Bash yourself in the head with it, hard
3: If not dead, repeat step 2.
