okay, thanks for the help.
I'm working on the save and load functions right now, but her'es an interesting tidbit I found:
basically, this is the underwater movement check. If you are underwater, your movement is slower. the possibilities for this are not quite endless, but are very cool, you could have the mimiga mask make you more agile, to make you seem more like a different character, you could make underwater have less or no gravity (space), utilize the water check for something else, like acid, have a suit of armor that you wear decrease your speed, or even add another check to the code. Another idea that comes to mind is in wtf story, you're never going to get life ups, but you could get agility ups by hacking the ml+ command, making you faster and with an epic jump height. Yes, this is a very nice piece of code. I hope you likes.
