As title asks.
I personally am a big fan of very ineffective, yet technically possible gameplay options in... well, games.
For when Juice Galaxy has become too easy once one has mastered the various weapons available, in my opinion it would be great - for gameplay difficulty and for customization's sake - to be able to simply use one (or both?) of our bare hands as very weak, short-range weapons, possibly capable of parrying common enemies' bodies yet incapable of countering enemy weapons (like Mrs. Slitherss' Draginslayer), for whacking enemies. This could be a great chance to test our grasp of footwork, distance, and weapon direction/control in Juice Galaxy.
