im not sure but maybe try making a better cover image, like instead of engine get a picture from the game

also your day 3 game was not in the collection you made

Having proper title, description and eye-catching cover is what you usually need in game jams to get your game noticed. For this jam, explanation of changes you made are a nice addition as well.

I wouldn't say that having some knowledge of the game is against the spirit of the jam. Telling what you wanted to do next would be.

After all, this jam differs from the video series in that we get to choose what we want to work on. Most don't have time to test many projects to decide so they pick whatever pleases them based on descriptions and images.

I belive the problem may be the art. People are looking for a game that can be expanded, and when they see that you already have a half-finished game on day 1, they will probably choose a game like Breakfast Wars, or Pogo Mining (If that was the right name), or Heist. I'm just saying, if you want to make a game more appealing in these events, make sure that art comes last. This is what went wrong with Lzer Not Found, and a few others. 

I'm experiencing the same, no one continue any of my participation, a bit sad but it's the game ! 

Day 1  Day 2 and same Day 3

I also work on Godot 4

And if it's cause of the Art and the "non-expandable" problem I get it. But the time you release the projects is surely also in cause..

Don't know ^^

I've no time left for the Jam but I wish you the best !
