Do you ever think about the silly flash games you played when you were younger and think "damn, I wish I could play it again?". NOW YOU CAN & THIS IS YOUR SIGN!!
Flashpoint Archive is a community-run archive that was born in the years leading up to Adobe Flash's demise in 2020. In the span of those few years, people searched the corners of the internet and saved as much Flash media as humanly possible-- they have about 150,000 games saved, not including the other pieces of media in their archives.
You can look up games in their search engine and using the Ruffle emulator (or the Flashpoint API) you can play all the games you missed :)
NOTE: Some of the games are non-functional, but the .swf are saved in the Archives for preservation. The Flashpoint community is still alive & well, and they have a discord server for anyone looking to contribute/hang out/give feedback!
