Half of the character designs were made prior to the jam by myself, but the latter like the enemies and bosses before Phobos were done during the jam! And all of the art and assets were made by me and Ryaninho during the project. That's probably the likely cause of the issue with the hit boxes, since our code for collision tends to get weird in edge cases (After all, we only had two weeks). Thank you for your comment, I really appreciate it!!
