Sorry for the late reply. I appreciate the interest. Here's a bunch of video links:

2nd (theoretically) Lightning Powered Arcade game (the LN integration was not quite complete) - the all custom Magical Crypto Friends Arcade Game, delivered as a surprise for Samson, Charlie, Whale Panda and Ricardo to the MCF Conference in NYC in 2019:

I have been working on a MCF Arcade Game v2 since 2020. The rona put a spanner in the works, but the game is functioning, contains many more Bitcoin (and crypto) personalities a few new features and new game levels (in progress). It also currently demonstrates LNURL-withdrawal so those who manage to complete the game can collect a reward. At some point I hope to finish the v2 and put it into a full size arcade cabinet. I'm looking for interest and hopefully a boost of motivation. :)

Thanks again for your interest and sorry for the delay.
