It would be cool if you added a gamemode where you could use a weapon of choice. So "All hands" or "Weapons" gamemodes, and you choose different weapons by clicking on for example arrows above the character to switch to the right and left.
That would indeed be very cool, at one point in development I considered adding throwable weapons that players could pick up such as shurikens or daggers, but adding entire weapons would mean there need to be a lot more animations so that would take quite some time. Still, throwable weapons could be added some day...
