Log messages are something I'm planning to add in the box that currently has the buttons in them; short little bits of lore and fluff that make the world seem a little more alive. The upgrade system, as well, is all going to have unique descriptions. Going to a restaurant, though, is a very neat idea, and I'll be sure to include that a time or two.
I did like random renamon boob clicker x, but that's mostly because it visually displayed particularly large sizes. Nothing else does that. Except now :)
It already does go faster the longer you go on; finding a new fox to grope will reset the size but increase how powerful your groping is. It's still a prototype, so the exact mechanism does, uh... exponentiate, after a bit, and the end of the game as of right now is the bit limit.
