The style and graphics are top notch. Really cool idea done beautifully! The post-it note tutorial falling off the screen is really a nice touch. I had some issues with the controls locking up until I refreshed the page. Usually after restarting but sometimes it would lock up randomly. The music is crazy loud, I ended up muting the tab. Take the same song, but some kind of filter on it so it sounds like it's coming from a tinny retro pc speaker, and lower the volume, and it'd be great. Great job overall!
