We're sorry to hear that you had issues, thanks for bringing this to our attention. I looked up the error, and it's apparently to do with the 60FPS limit we set. I don't entirely think it's what's causing your 1FPS issue, it might help if you tried playing on a different browser. All our games for instance seem to have issues on Google Chrome. If that still doesn't work, we plan to add downloadable versions when the voting period for the jam ends.
