I'm so happy you were able to finish a game for your first jam! Not that many people are able to complete a game on their first go! It can be tough trying to figure out scaling for a game, especially as a first time solo dev, but I think that mostly comes with practice and understanding your limits as a developer, like figuring out which skills you're good at and which of them you need more practice on. Either way, I'm happy you were able to complete something - hopefully you managed to learn a lot for your next game jam! I think you did, so don't be discouraged for your first jam - you already have a lot of lessons to apply for next game jam! Wish you the best of luck with your future endeavors!
