Hey, I'm making mobile game called EPIC IDLE RPG. Its over year and half of making it solo. Lately I hit performance(20-25fps) issues on 1920x1080. I started thinking about moving game logic into web worker, but it's big task to do. I use mostly preloaded pixi.sprites, pixi.animatedSprites, spine2d for characters and webm videos for backgrounds animations. What I can do to improve performance?
Here how game looks:
