I've recently forked and repurposed an e-commerce site for this purpose, it is in a very preliminary state, here is the link:
https://codeberg.org/glitchapp/Game-grid
Beware that there are mistakes on the testing site regarding the developer of the games listed, platforms and other fields may be wrong... since it is only a deployment to show and test the site.
If you want to test the corrected and last version you need to download the source from the repository, install it and run it with npm.
As explained in the repository, my only goal is to create a "game search engine" and help people browse, find and download games, but I´m not endorsed by Löve developers nor I want to replace the official game list.
Feel free to let me know what you think, I will try to improve it through feedback
