Hi Ataro!
It's awesome to hear that you had a good experience; we're so glad! The best part of any event like this is the experience and the development journey; we always like to think that the best jams are the ones that you walk away from having learned something!
That being said, we'd still love to see your game in Core! Keep up the hard work, and feel free to let us know on the Core Creator Discord when it's ready!
