A two months long jam dedicated solely to all things underwater!
Be it deep sea horrors, fishes, or bacteria living in a puddle down the street. As long as it primarily concerns something existing below the water surface, it counts!
You also get a few buffer days on top of those two months, to account for those times where life inevitably happens.
Generally the rules are pretty broad and as long as a typical player could, without a doubt, consider your work to either take place mostly underwater or deal with water creatures and so on, it's fine. Octopus tentacle monsters, mermaids, discovering Atlantis, or just chilling deep diving are only some of the examples.
If you have any doubts about your entry, please refer to the FAQ. Or feel free to hit me up [Awiola] on discord/tumblr/the jam forum.
With an idea, of course!
I recommend checking out the FAQ, which expands upon the information below, but in short:
If you're new to visual novel, or otherwise story game development, some of the most common engines would be Ren'Py (made purely for VNs); Unity (with its many templates, like Naninovel); or Twine (perfect for some interactive fiction).
And if you're looking for a team you can always check out the jam community, one of the linked servers/sites, or gather your friends to make something. Or solo dev. Any combination is fine :D
DevTalk — while not directly related to the creation nor hosting of this jam, it's a helpful community (on Discord) for visual novel creators that also makes finding group members for future jams easier.
Lemmasoft forums — for your Ren'Py and dev needs if you're not a fan of Discord.
