I also had the jump bug so I couldn't play the actual levels (tested on both firefox and chrome). However this is such a cool concept and everything else is so well executed that I can't hold it against you or the entry at all.
Animations are super juicy, the lens effect on the spectacles is incredibly well implemented. Also the music fits really well with the rest of the aesthetic.
Great job on this one and good luck for the rest of the jam!
