The web version I find it cool from a technological perspective and while I agree with you on the slowness of Javascript apps vs native apps in general, WebAssembly is a completely different beast and you can have very good performance with it while benefiting from all the portability advantages, it’s basically what Java tried to become with applets back then. It’s cool because you can also have stuff like a whole Jupyter Notebook run locally in your browser without installing anything, which can be useful when you have to teach Python and you don’t want to deal with students not installing their stuff before the class begins: https://github.com/jupyterlite/jupyterlite .

FYI, the OpenLara GitHub repo I linked to also has native builds. In particular, it hilariously has a Gameboy Advance build: https://www.youtube.com/watch?v=_GVSLcqGP7g
