Smile Inc. Guide: How not to die on the job

As if Mondays weren't bad enough, at Smile Inc. you have to deal with giant killer donuts, massive hungry staplers, and blasting zones. It's not exactly a happy, thriving work environment. In fact, you'll be lucky to survive the nine to five. Smile Inc. is a tough little endless runner, and it often tries to trick and entice you with precariously placed rewards throughout the levels. Don't fall for it! Instead, follow these handy tips to ensure you make it through the day.
The game doesn't really point this out, but you can actually earn a large number of gems and mystery boxes by completing missions and overtime. These prizes aren't just handed to you, though. You'll have to return to the main menu and select the little prize ribbon. Number indicators let you know if there's a prize waiting to be collected. You'll find new characters and rare hats this way, and while they don't really do anything to boost your survivability, they sure are fun. Don't forget to jump
I know. It's the first (and really only) thing you learn how to do in the game, but you'll quickly forget it when you're distracted by all of the razor blades and land mines. However, if there's an obstacle on the ground that you absolutely can't dodge, tap the screen to jump and get out of the way. Keep in mind that you can't run while on a caffeine rush, and that there's a cool down timer after every jump you make.
Keep an eye on the red warning indicators
Yes, woodchippers and giant scissors are scary, but there's a little leeway. You'll notice sliding red warning indicators telling you when an obstacle is about to kill you. You can safely run through dangerous areas as long as the red indicator is moving away from you. Worrying too much about avoiding all danger zones might do more harm than good, so it's sometimes easier to look out for warnings than avoiding everything in your path.
Smile Inc. does its best to throw you for a loop, but with a little forward thinking and the tips mentioned above, you'll be promoted in no time (and you'll probably have a pretty nice hat collection by then, too).
