Lantern, sprite util, better arrays and settings, timers, sprite data, extra effects, character animations, shader and all the rest are extremely complex and took a lot of work and effort.
I coded my own shader for the mini game jam on boss rushes and it was complicated, huge and still very inefficient.
All this just to replicate the lantern effect, even then it’s still a worse copy of it
Try recreating any extension, maybe the Arcade-mini-menu extension
