I love that you have a README and License file (main criteria for open source category). I'm enjoying the TODO list and the fact you are ticking them off as you go. Maybe build all the "done" ones into various releases so the README doesn't get too long, or even make it a changelog file. Add some screenshots to your README to make it a little more interesting too 💖.
Wow, this game is huge, and gee can that witch jump! Great work. The sound effects and music fit perfectly, and the art style is great. In future you could probably add some more levels. Well done on a great submission.
