Is there potential?

I made this game as part of a game jam because I really liked the theme (I generally love holiday themes in game jams). I shared links to the game here and on Reddit and received a moderately positive response, meaning that, overall, this prototype brings people some fun. Now I’m a bit unsure: should I make a full release with everything I could imagine for this game? Should it be a single-player campaign or better as a multiplayer?
