I kind of made this for inspiration when I feel like making levels is impossible Use turbowarp. https://turbowarp.org/1390218450 or this https://codetogch.net/scratch/1390218450 replace the g with an r (make an account and remix it so you can play it again if you want to!)
this is my most detailed level with exactly 100 backdrops, and I'm not even done with the effects yet. I might even be able to say THE most detailed level... day 1 - started the chart and made a few backgrounds day 2 - finished the chart and backgrounds day 3 - realized all of my progress on day 2 had been wiped and gave up day 6 - finished the chart and backgrounds, again (the backgrounds may have less detail... also there were originally 125 backgrounds) day 18 or so - started adding effects and added a loading screen, released the project future - finish effects
