Switching weapons between dimensions is a good concept. I haven't seen anything like it in this jam so far.

Cool stuff. Wish my bullets wouldn't be stopped by other bullets. Switching mechanic was interesting, would probably be more intuitive if you clicked and dragged the weapons to each side.

I couldn't get the weapon world switching thing to work, the weapons just got stuck where I didn't want them. I think you were on to something here but that you didn't get to a fully realized enough game to really do the idea justice.
