Right now, to fire a long-range weapon you have to press A for Aim, put the cursor on target, and press Enter.
Now consider what Noxico started as: a ZZT/MZX clone. In those games, you fire your weapon by holding a modifier key and pressing an arrow key.
If your target lines up with you, use shift-arrows, and if it doesn’t, use Aim mode. Sounds okay, right?
