Game jams are useful for getting something done but they rarely have the polish of completed games. Even if your game was successful, you may want to go back and polish it a little afterward. I learned a lot from my failed entry. I fixed it a little afterward but it still needs a lot of work to be complete.
Looks like you are using Game Maker Studio. Have you tried asking for help somewhere? I'm not familiar with GMS. If you can't fix them maybe try some tutorial and a simpler project.
(I have been playing with Godot after seeing Disc Room Game Jam's example GMS project. I mostly recreated it in Godot and have been modifying it since them to make my own creation.)
