OH MY GOD YOU GOT BILLIONS! I myself never earned that much, my congratulations!
About your comment, yeah, a game have a fundamental design problems, its just like a math problem, you know everything you dont jave to make difficult choices, you can just calculate. i eas thinking about making a deck and let player draw cards every turn, but it just a whole new game and balance... So I decided to practice how to make tutorials and end this game(You probably played the older version without good new tutor and a character). But that was my first game, so next one will be better)(I hope)
