It looks like Itch has a way to add games that missed the deadline to the game jam. Complete the following steps soon to have your game added to Houdini Game Jam.
1. Add the following questions and their answers to your game's description on Itch:
-Team Name
-Game Name
-Contact person name and email address
-How was Houdini used in your game's development?
-Besides Houdini, what other tools did you use and what did you use them for?
-List any content that was created before the jam that was included in the final submission.
2. Send me an email at ben [at] sidefx [dot] com that includes your game's Itch link. I will reply with a custom URL to use to add your game to Houdini Game Jam.
For reference, these are the games that are being accepted during the grace period. No other game entries will be accepted.
