This jam is now over. It ran from 2022-04-05 04:00:00 to 2022-05-01 03:59:59. View 92 entries

A lot of people have told me that the first Caltrop Core game jam was their first time ever making a game! I'm so unbelievably honored, I can't even explain. And with version 1.0 finally released, I figure it's about time to show off what we all learned the first time around!

The only rule for this jam is: Make a Caltrop Core game before the end of April!

If this is your first time making a Caltrop Core game (or a game of any kind), welcome! You can get a free copy of the standard reference document (SRD) by clicking here:

Join my Caltrop Corps Twitter Community here: That's where we'll have discussions and where you can ask questions of other game designers!

And now for something REALLY special. I'm announcing...
