Recently, generating things randomly has become popular. It adds a very entertaining layer of replayability if the game isn't too long, so it could be a very good improvement, though perhaps too complex to implement. Survival games are difficult to balance in all aspects because there are so many interrelated mechanics. But what stands out most about your game, in my opinion, is not just the gameplay but your "humor." Maybe you could give it a twist, like a plot twist in the genre, similar to the movie "Cast Away" with the Wilson ball, you know? You could engage the player more with the aesthetic and story, mixed with survival on a deserted island, but making that aspect more secondary. That way, it could turn out to be a great title.
