There's nothing about the game you uploaded that makes it a game - it looks like it's just a low-effort motion to just get a free course and goes completely against the spirit of the game jam. I downloaded and played it myself - it is just a texture-painted terrain with a bunch of cylinders; there is no gameplay. Not to mention the description of the game is completely misleading, given what the "game" actually is.
I reported the submission as invalid, FYI.
Did you...post on your own game's comments and say, "very nice game"?
There is nothing wrong with being new or making something that's not great. I think what people are calling you out on is being purposely misleading. If you are new to game dev you should own it and be upfront, but also put a little more effort in at least making a gameplay loop.
Good luck.
There are still 4 days left in the jam, that's more than enough time to make some additions and improvements!
You should try to add a bit more to your game, and use some assets to improve it visually. I completely understand how difficult it is as a beginner (I only started learning Godot in October and I remember the first few weeks where nothing made sense to me), so try to find a few simple ideas to add just so there is more gameplay, as right now it just seems like a very basic walking sim with nothing to do.
And as others have said - try to find a gameplay loop. The games in a game jam are generally very short, so the way to keep the audience entertained is to add a gameplay loop. For an example of this, Vampire Survivors started out as a game jam entry. So even adding something as simple as having a timer and things to collect, and seeing how fast the player can collect them can create a gameplay loop.
