No matter how well the statistics have said you've done today, you've made a video game. That's a fact. You've gained experience. That's a fact.
What isn't a fact is what you will do next with your project. You all have something incredible, so I really hope you decide to continue working on your game - make it a full release, put it on Itch.io and Steam.
Submit your jam creation to national competitions (if you're between ages 10-18 in the UK, I'd highly recommend you check out BAFTA YGD and submit your game there for next year's initiative). Even if you don't think it'll go anywhere, please do run with your concept further. Make more levels, fix that one bug or add that one cool feature someone mentioned in the comments!
Please keep developing this game you've made. It will be worth it.
