100% agree!
I plan to combine my prior game jam game and this game during March.
The major change will be that you can throw a ranged weapon by mouse clicking/holding. This will allow attacking enemies that make it past the orbit.
I also want to have the start button go to a screen where you don't know which character you're getting, and you pick one of the "reveals", then the weapon, you can pick one of them.
One of the reasons why I did not add more swords is due to performance issues around the radius updating and rotation. With enough of the weapons circling the game would grind to a halt. However, the player can get the same thing with enough attack speed on a single weapon.
