I have the flash standalone player on my pc and have downloaded approximately 35,000 flash swf files which run good as far as i can see.Plus i have palemoon browser for the flash plugin which palemoon still supports for the tricky games which don't work in the projector.
A lot of stuff is on the internet archive too including bluemaxima .
it was indeed sad to see flash go but i still trip the light fantastic with the setup i have.
The old site to create puzzles and games no longer exists (404), that's why I put this one, in case someone wants to create a game of this type.
Just put the title, the subtitle. Choose the difficulty and size and put the words to search.
