As part of some work I've been doing to help optimise a @gbstudio.dev project I've put together this tool that other people might find useful codepen.io/roastb/pen/X... it lets you drop in background pngs and it merges similar tiles + creates a common tileset image

Working on some tools to help diagnose slowdown in @gbstudio.dev games. Can scrub through recordings and see what was running each frame. Already found a few easy wins for optimisation coming to the next release! Code up at github.com/chrismaltby/... if anyone might find it useful (plugin devs?)
