So there is one problem but every thing else is great. The problem is, It is lacking in the feel of the game.
You could do is add some music because it just sounds empty when your playing.
You could also add some cheering in the background too.
You could make different modes like 4 players and they have to be the last one standing or first to eliminate someone.
I would play this game with my family and I really love what your doing.
