Hey! your art-style looks amazing! Really love the style of the sketches too. I would go for a game with that style if i where you would look so original! Very nice UI too. During my project I found out I'm Horrible at doing the ui/ux part :P
Sounds great that you took the step in trying to make your own game and getting it to work :) Think its a good thing to join game-jams, just to force yourself to do something new or as extra motivation to work on a project. Depending on the gamejam :) I did encounter a bunch of the same errors on mac I'm afraid... Don';t know what program you used to make this but i could skip the errors so that was great. I can send you a screenshot of the error if you want?
But overall good luck with the rest of this project!
