Actually Rocket Science

You and your friends are the crew of the world's cheapest space program, and you have to fly an actual rocket to the Moon, and then to other planets.
Reach your destination using a wall of about four hundred switches and buttons.
Then upgrade your ship and do it all over again, farther.
It's only rocket science. How hard can it be?
This is the most autistic game you can play on Steam right now.

In this game, you and your friends are the crew of the world's cheapest space program, and you have to fly an actual rocket to the Moon. The capsule is tiny, so try not to elbow the abort handle.

Once you're strapped in, you are met by a pretty intimidating task.
You have to launch, separate the stages, survive three days of space, and land on the Moon — using a wall of about four hundred switches.
There's a checklist to guide you through them.
It's photocopied, page six is missing, and the friend reading it out loud has never been right about anything.

The detail in this game is absolutely insane. Almost every switch is flippable. You can eat beef stew from a tube, and yes — you can use the space toilet. There's a checklist for that too.
Anyways, once you're finally off the pad, you're gonna want to keep your eyes open, because things will go wrong.
The oxygen can fail on its own, or your friend flips the wrong switch at stage separation and turns the mission into a very expensive firework.

And if you start getting on everyone's nerves up there? There's an airlock button. Your friends can vent you straight into space. No meeting. No vote. Just stars.

Stick the landing, plant the flag, say something historic.
Crash, and the crater gets named after whoever touched the panel last.
It's called ACTUALLY ROCKET SCIENCE. Because it is.

You can reach many different planets and moons.
Use your hologram space map to navigate the star system and reach a planet or a moon.
Once you land, you can explore and gather resources to upgrade your ship and go even farther.
(If you can manage not to crash it)
Some resources may also be found during space-travel, where you'll have to space-walk out carefully to collect them.

You can go outside the ship in space for a space-walk to repair broken parts or collect resources from asteroids or space debris while your friend is holding the cable, desperately waiting for the moment to let you go floating into space just cuz it'd be funny.

It's basically a friendslop space exploration game.
Friendslop meaning it's way simpler to understand, way funnier and fun with friends, and way more replayable.
Think No Man's Sky's space exploration but it actually plays nothing like it and it's specifically made to be more fun with friends, but can also be played solo!
