I will update with more decoration at some point. Or maybe I'll take the deco out if it's causing the lag. It is not very good because I lost hours of progress due to Scratch not letting me save the project and forcing me to download it instead. Maybe it will get fixed soon, but so far it's not looking good. If anybody knows a trick that will let me save my level, please let me know soon.
