Longgame Tech Innovation Jams are about promoting interesting, innovative art (especially with Lisp) and sharing it (especially open source).

It's a week long, then a week to vote on the submissions.

The jam focus for LTIJ1 is time.

Here is Longgame Tech's Discord server (permanent invite link): https://discord.gg/Jew7WXrAvG

Categories

There are 3 categories: Innovation, Lisp, and Open-source.

This game jam is about developing fun and interesting mechanics, promoting and encouraging Lisp, and public sharing of art.

Devving with Lisp isn't required, but there's a prize for highest-voted innovative Lisp game. Lisp is a fascinating mathematical macroing language.

"Open source" doesn't have to mean that anyone can use it, just that it's publicly viewable. I personally like the license of "you can use this art in any project for any reason, just please provide a reference back to the source". An example of that is essentially 0BSD or the Unlicense.

Prizes

There are 3 separate prizes, one for highest-voted in Innovation, one for highest-voted in Lisp, and one to a random Open-source submission.

To be fair, the prizes can overlap, so a single person can potentially win all 3.

Each prize is $15 for innovative games of your choice from Steam/itch.io/GOG/etc. Examples of innovative games: Braid, Portal, and Induction. It's up to you!

FAQ

What is Lisp?
Lisp is an abstract language discovered at the end of the second millennium (late 1950's). It is about list processing, usually of symbolic expressions (s-exprs). It is one of the biggest languages for developing intelligent machines (AIs).

What are some games with innovative time mechanics?
There is a fairly detailed list on Wikipedia of games about time.
