Sorry. most features like the music aren't added yet.. *sigh* I added them into 0.8.1 but I added a bunch of stuff in the editor that are needed but may break this version as well.. Can't you edit v0.8.1 using Scratch 3.0 to figure out whats causing the lag. Scratch 3.0 lags if there's an issue but doesn't crash like Scratch2. My gut is telling me that I won't be able to develop PlatformerCraft in Scratch and if I do I'm probably not going to build on it. I think its safe to say I reached the limits you can do with Scratch and will move on to Unity and C#. I'm kinda feeling uninspired to work on the game on Scratch when I know I won't be able to.. At one point in the game's lifetime I may not be able to update the game.. Scratch can't take it... I'm just sharing this so you don't have to wait for me to add all the features.. (I think I'm rushing this game)
