Iain and I just gave a workshop on creating online games using Phaser3 and CsoundWASM. I've put the up info and examples here. @iainmccurdy showed some really great procedural instruments which I blatantly robbed and also pushed to the github repo! If any of you make new levels with this simple framework, please make a pull request so that we can host it in the same place. I'm happy to answer any question you might have.
