It's the most advanced PHILPHORMER ENGINE so your welcome make sure for background,background 2,death stuff and foreground as well as ground design that it always has as many costumes as ground. for foreground and death stuff it can just be nothing but still be a costume. ground is what Phil actually walks on and is the actual shape of the level while ground design makes it look actually good and not just purple blocks. you can turn off paralax scrolling if you want with the button at the top. You'll have to do extra coding to change health or add enemy's or something.
This uses some code from older projects I made so it's still techniccly my work
