just to clarify, you might want to ban the level skip cheat. (not that it wouldn't be implied, but ye) either that or make a cheat category, but obviously that'd just be typing this like 15 times or however many levels there are. this is the cheat (this was from thedailyneopets site.)--

Type "quaglor" to skip to the next level. You can use this cheat as much as you want; however you won't be rewarded with any points.

Here is a video showing an example of that. --
