Some combos are reset every time you retire.
So if I retire 144 times in a row, I can select the same combo every time and my bonus will go up way fast...
If you're trying for the "powerful red" achievement, once you've got everything fully upgraded, DO NOT try to dodge anything. You'll lose more speed maneuvering than you'll do by hitting stuff. Just hold the turbo button and you should be fine.
To those complaining about achievement bugs: a soft reset should fix that.

Once you hit 200 everything and a decent number of Investors, is it better to go for 300 oil companies straight away (since they're the asset bringing the most money anyway) or logically, from lemonade stands on (though I've read the prices cease to increase in logical progression)?
One day, developers will understand that you simply need to click on the "like" links to receive the money, without having to go through with said "like".
Meanwhile, I'm enjoying the free bonus.
It's under "3 dots" button
