Per title, current orb system for the pc is kinda bad (especially for PC players playing with keyboard) since RNG-reliant and binding keyboard to many keys didn't help with focus on which button to press. If I were to redesign the In-game UI, it would be along the lines like the one Flamebeau have right now, except:
- Each orb can only hold 5 orbs/color
- OR dynamically limit on how many orbs can be held, like if there's 9 red and 6 blue, then you can't get any yellow, since there's 15 already.
