Money Maker is a game where your goal is to make A LOT of freaking money. With said money you can buy buildings that will help you make A LOT MORE money, stuff like vending machines, money printers, etc.
This is a click-and-play idle game for children. It's easy to understand with Japanese (and some English) text, and playable with just a mouse. When you're busy, let your child play this game while you get things done.
