I think I found them all? Our team backseated me while I was playing and we turned the entire room over and found 3 games, not sure if there was a really well hidden 4th one but my favorite one has to be the Galaga/Snake one! I don't know if it took direct inspiration from any games, but I thought it had a unique mechanic and got tense at times, which is impressive for a game inside of another game jam game, let alone a game jam game in general. Really great work!
