Is all this original work? The music and the visuals are really nice. That boss theme was great. Obviously have some things to tweak as people mentioned. I stuck with it until the end though, which is a testament to the quality.
Yes, all the sprites, animations and music are original! 3rd party assets (with some exclusions) aren't allowed in this jam as far as I understand. I'm very happy to hear that you stuck till the end and completed the game! Thank you so much for playing! :>
