With what I saw your world is a scavenger hunt game.
Great job on your submission, you had many neat features. Liked that you had a UI that tracks your progressive and I like the portal effect for the spaceship.
Progression
I saw picking up artifacts (primary goal), keycards to unlock doors, it is progression, but compared to the winners it doesn't seem like enough progressive elements.
Sharable
I find this one hard to say and unpredictable. Maybe space station could be a cool place that people may want to share, but its possible that there isn't interesting enough scenes to be sharable or not obvious enough to say, dang I could really see people sharing this.
Possible Improvements
I think making your world and UI more visually appealing, would have helped. Maybe as well making the scavenger hunt more engaging like having to complete a puzzle to get it, or other game features. Add more progression, like as you get more artifacts you gain level/rank and it unlocks wearable (badge) for the player. Add some areas that are really interesting, like a alien attacking that puts the camera at a good angle to take pic. Improve your video submission.
These are just my opinion, trying my best to do research (researching winning worlds) and improve my own world so hope it is helpful. If you want you can give some constructive feedback here instagram.com/reel/DNE36-LNmFT my submission is devpost.com/software/fractured-party-games-updated .
