To start with, I want to say that you should feel proud for making something and submitting it, that's a pivotal first step that many don't get to. Everybody has to start somewhere and this is it for you.
On the positive side, I like the art. It's quite cute, especially the player character.
On the less positive side, the main issue I have is the lack of engaging gameplay for the player. You can make a "walking simulator," but those require more than just walking, like an engaging story and characters. If the gameplay you're going for is the random paths, there needs to be more gameplay and player agency surrounding the mechanic. Right now you can just walk any direction and eventually end up where you need to. The player doesn't get to make any meaningful decisions or interact with anything to make this happen.
I do think there's a workable idea here. Randomly generated levels with a fetch-quest goal like this can be a fun loop for a roguelite, for example. I suggest for your next project to really hone in on what makes the game fun and engaging for the player and build around it in a way that gives them meaningful gameplay and decision-making.
Keep going and making games!!
