The Flashpoint Archive is a big project to preserve old web games (Adobe Flash based games, animations etc).
It has a really cool video about what it does on its website: https://flashpointarchive.org/
Go check it out. It’s literally a treasure trove of old games.
Here are some screenshots:
Flashpoint is amazing. I’m in game dev school and every time someone comments about missing old browser games I show it to them. Seen a couple people get excited to tears being able to play childhood games they thought were gone forever
They also have a linux version of the launcher/manager
understandable 🥲
