Honestly, it was a pain for me to decide what would be the best option for both Firing, Equiping and Ejecting TWO weapons at the same time, specially with a Gamepad in mind. In the end, I decided it to be the same buttons for equipping and ejecting each weapon separately.
One option I was considering was to make the Ejection action more like a Hold Button for X seconds instead of being instant, and the issue I wanted to avoid the most is to accidentaly eject a weapon when you just want to equip it.
If I come up with a better solution, it will be added in a post jam update for sure.
Nontheless, I am glad you enjoyed it!
