Glad to see you’re interested!
Actually there’s more - Spring Thing voting lasts all through the jam, and LibreJam voting is 8-14 April. Parsercomp games should be submitted by the end of June I believe. And after that there’s IF Comp. And I’m sure there’ll be other comps or jams in the fall. I don’t think there’s a better time than this if we want to throw a jam in 2021, and life is too short to put it off to 2022. I talked to Adam Sommerfield (ParserComp) and Chris Ainsley (TALJ), and both thought this was as good a time as any to do this.
I do hope this will work more as a (welcome) kick in the butt for a few people to learn PunyInform and use it to create something, sharing and cooperating with others. The competition part is truly secondary, and jam entries that want to keep out of the rating process are just as welcome.
As for porting or translating an old game: The idea here is really to produce something new. The time frame is limited, and we’re definitely expecting shorter games - something that’s new, finished, not terribly buggy and provides 15 minutes of fun would be just great.
Also, a theme will be announced when the jam starts, next Friday. This is something that you will somehow need to include in the game. Hopefully it will work as an inspiration and get your imagination going.
But if you’ve written a game which hasn’t been circulated, and you find that it works with the theme, who are we to say you can’t use it?
