Basically, the aim of the game is to fill in as much area of the level as possible. The game gives you the amount of level filled as a percentage. Changing this value to end the level does not work as it only displays the value here and isn't stored here. So I ran a debug on the game via "find out what writes to this address."

I was given a single command;
00434997 - 89 1D C87E4500 - mov [00457EC8],ebx

So basically, the percentage was copied from somewhere else. What is ebx? What can I go about doing to hack this game?

If required: The game is called Water Bugs.

It's a demo. I downloaded simply because it's a very simple game and should be easy to hack.

EDIT: also, if I set the search to 4bytes does that mean I'll miss all 2 byte and lower addresses? Am I searching the capacity of the address?
