Well i have two suggestions, 1: make a button somewhere leading to a readme.txt for cheats, telling you how to use them, i have been trying for a while, and cant understand what i been doing wrong, and the red letters could be black to match better with the screen, you can also make them bold

Also it would be nice that it would be a list checkbox, where when you check it, the cheat is on, and when you uncheck it, the cheat is off

it would look cooler, and again, simpler.
