Hey,

It’s a small thing but looks like when a jam prevent people from seeing the others submissions before the deadline, you can still see them by uploading your game, going in its page and download your executable, you will have a popup with “Check out more from [jam name]” with the others games

This is intentional. It’s not meant to hide someone’s participation in the jam, but to prevent a single submissions page that is potentially seen by a large number of people. Some devs find the need to try to exploit that page to promote their projects by spamming their entries into the jam as soon as its open.

Ah I see, thanks for your answer
