The money is your score (the amount of damage to city). I'm not sure why the xp stopped increasing at 117, I haven't had that happen yet. I'll add it to the bug list

Also, you can keep reloading to do the tutorial and it saves the things you've done before you've finished it. So you can build stuff, then reload and keep the stuff you've built.
That's very odd. Make sure you give the game a minute(10+seconds) to load, it's kind of big.
