This project has no keyboard interaction, but if you hold down a key (at least in chrome on windows) the FPS goes from 2fps (fullscreen) up to 3fps, but the actual refresh of the page is obviously dropping to like -555555555555555555555555555555fps! Crazy scratch! - If the Scratch team can fix this then all the excellent, yet laggy projects will be oh so much better for it!
