A major bug fix, an update, and an itch page tweak.

I changed the color of the page from pinkish-purple to blue. Thanks to those who let me know via comment / uprating that it was an issue for them.

A version of the bug I fixed in the last update, the Goth Girl not showing properly at one stage, also affected another character, but I didn't pick up on it until today. That's been fixed.

I added a difficulty selection screen, since enough people complained about how fast they had to click. I've playtested this thing front to back something like twenty times, so I thought it was in spec, but public consensus seems to be that I have an unnaturally quick clicker finger. A laptop mode, that assumes you can't click at full speed for mechanical reasons, and an easier-than-easy mode, which is basically a cheat to make losing a cycle/loop/city extremely difficult, are now available.
