Is this more for proof-of-concept / tech demos as opposed to finished games?
I can see that existing projects are technically allowed, but that doesn't seem to be the intent.
Viewing post in #1 Playstesting Jam is on!
it can be for finished games, as long as you respect the rules! If you have a finished game and want to test with players you are free to submit it.
we believe that mostly people will submit early demos, proof of concepts and alpha versions, but as long as you are comfortable with submitting your game for testing you can! The idea is to have a space for devs and players to collaborate with each other.
