Yup sadly a great big bug must have somehow weeded itself out of the game and into... well the code which is technically the game but that's not the point! The flicking seems to be messed up due to different monitor resolutions (which I've learned is what happens with Rhythm Heaven on upscaled emulators too!) so anyone without a 1440p monitor like mine should theoretically have a hard time getting the flicking to work.
Thanks for the compliments on those animations though! They aren't the prettiest but I thought they were a nice bit of extra fun to add in nearing the end of the jam. If only I knew those darn bugs were hungry enough to eat up whatever ratings I could have gotten for this jam!
