Nothing much just get as much money as you can. Press the C key on your keyboard to change what the money looks like. There is normal money, a cat and a dog known as Doge from the memes. Follow, like or favorite my games for more games. The load button does not work at all by the way. Sorry.
I made everything but the code for the load and save buttons I followed a tutorial on youtube from DKuniverse I recommend watching his tutorials.
