Yes! You are of course welcome to game deving, and it is good to start on a game jam. My criticism are meant to improve the game, I'm sorry if I was being harsh. I'm glad you learn a lot of game jammin,g and it is one of the best experience to get for game dev in my opinion. One question I have though is how is your game fitted with the theme.

Bro, congrats on joining your first game jam man. First, game jam usually have a theme that is released when the jam started. For this game jam, the theme is 'calm before the storm'. Which your game should be design to some what fit the theme. For example, you could say 'calm before the storm' is a metaphor for a brief period before something chaotic happen and build a game like preparing the store before it open.
You could interpreted the theme anyway you want as long as it is based on the original theme.
Anyway your not selfish and don't be sorry for the game not getting likes. Game jam are meant to improve the process of making game, and everyone got to start somewhere. I'm sure people did not meant to insult you, and I apologize for my first commenting being rude.
Great jobs on your first game and welcome to the world of jaming!
