We Are Doomed is above all a 2 twin stick shooter that is quick to get into but hard to master. Learning the game itself is about a 1 minute tutorial, assuming you read very slowly.
You control a small ship, that basically looks like an odd shape and you shoot other ships that are of various shapes and sizes. The game should also probably come with a seizure warning because this thing has more flashing lights that anything has any right to have.
The game is a blast tho, you can fight wave after wave of ships until you die trying to get a high score. Your other option is just endless enemies to see how long your survive. There is no story at all and no real point to the game beyond that, kind of like an old school arcade game. That is actually where your issue will come in to this. If you okay with just some mindless fun and a challenge, you are good to go. If you are more of the every game needs a purpose and story with a well-defined purpose and motive, this game is definitely not for you. Best wishes, and may the gaming gods bring you glory.
