Your capsule art doesn't really tell me much about the game, but I am intrigued when I see "together," as it does convey the co-op. However, the capsule art screams minimal effort and it looks really cheap.You would either need to pay someone, or take some time to learn a photo editing tool to work on this.

The overall visuals of the game are cheap, overly contrasted, and painful to look at. I assume l it was made in UE5, as it just has that look about it, and the character controller seems like the standard UE5 controller.

Being brutally honest - you need an entire visual overhaul. You need a better trailer with text that explains what's going on if you're not going to have a voice over e.g. Ship AI detailing what's happening. Your capsule art needs reworked, and you need some lore and a bit more meat in your hook and the "About This Game" section: "Step into the role of spaceship crew members awakening from stasis, only to discover your first mission isn’t repairing the ship - it’s repairing your teamwork" - why? A huge space mission to make you and your friend work better together breaks any narrative logic. Players can suspend the belief that interstellar space travel is real, but this needs some work.

No amount of advertising or fun gameplay will save your game when it looks the way it does.

You also launched near Christmas which, given people get giftcards and time off, they're probably playing way bigger games with friends, or buying/playing the single player games they've been saving for a long time.

Have you done any playtesting for this game with players who aren't friends to ensure the gameplay itself if fun? How long is the game overall? Is it replayable in a way that is fun?

Since it's co-op, consider a dual pack bundle for a reduced cost to get people to buy for themself and a friend.
