Sucked out an airlock? Murdered by a crazy alien drifter? Teleported onto an alien ship and forgot to teleport back before the ship blew up? There are seemingly hundreds of ways for your adventures in FTL: Faster Than Light to come to an abrupt end.
One of the reasons the game is so tough (to beat and to put down) is that it's totally randomly generated. You never know what sort of ship battle or encounter is around the corner, nor do you know which decision may be your last.
Thankfully there are ways to get a leg up. One way: take the advice of the game's co-creator, Justin Ma, who kindly provided Polygon 10 tips to keep that spaceship afloat and your crew still breathing oxygen (presuming the crew has lungs).
Blue text choices are almost always the best ones. They are guaranteed to be the same or better than their white counterparts.
Ride the Wave
Enemies will get harder each sector. To keep up with them you need to constantly upgrade your ship. Try to stay in each sector as long as possible to get enough scrap, but try to stay ahead of the Rebel Fleet.
Don't Forget to Breathe
If you temporarily swap power away from the Medbay or Oxygen system, don't forget that the game won't automatically turn them back on. Many a crew was lost to forgetfulness.
Or Just Hold Your Breath
Teleporting onto an automated ship is usually death since they carry no oxygen. However, if you upgrade your Teleporter to use 2 power, it gives you enough time to retrieve your crew before it suffocates (just don't send a Zoltan).
Maintain a Health Buffer
You may be reluctant to upgrade certain systems/subsystems because they seem unnecessary. Don't forget that each upgrade is an additional damage [buffer] that room can take before the system/subsystem shuts off. One extra bar in Oxygen can save your life.
Farm the Clouds
The Rebel fleet will approach slower if you are in a nebula. When you're prepared stick to the clouds to get some extra scrap before the fleet arrives but be wary of the increased threat of storms.
