>>22861078The thing that felt the closest to me was getting one of those big itch.io bundles (the BLM one, I wanted the games...) and just trying out random games from it. I think there's also html5 browser games on itch.io Idk if they would scratch the same itch (no pun intended).
You could always install Ruffle and play some old Flash games from Newgrounds or the Flashpoint archive too.
