Hello LSDJAMmers!
The jam is going to be coming to a close within the hour - so if your project is good to go then now is the time to submit!
However: if your project is not in a good state, then all is not lost. Life can be tough, especially in 2020. For this reason I'll be allowing late submissions up to weeks after the official end of the jam (tonight).
How do I submit late? To submit late, simply keep making your game as normal, and when it's done upload it to itch.io regularly as if it were a game not part of any jam. Once you've uploaded it and have the link, DM it to me (I'm @Figglewatts on Twitter, or Figglewatts#9876 on Discord) and I can generate you a one-time game-specific late submission link for you to add your game to the jam.
I will be using this process myself for my project, as life got very much in the way towards the end.
Additionally, if you were too busy in general to make anything for the jam, I can excitedly confirm that LSDJAM will be returning again at the same time of year in 2021.
I look forward to playing everyone's games, and I hope to see you all again for LSDJAM 2021.
