We'd also like to thank MrPinball64 for acquiring these prototypes and letting us release them, as well as Billscat-socks for doing all of the documentation and playing them on our Twitch.

Enjoy, everyone! And for those in the northern hemisphere, enjoy your summer!

But that's not all!

Presenting, a previously unreleased game – a pitch for a NES game called Scanner. Thanks to @frankcifaldi.bsky.social for providing this one!

(I've lost count how much good stuff Frank has contributed just this past year)
