Thank you very much! 

I would have gone with a tutorial to explain how everything works, but I didn't have time for that (started half a day late :P) 

I am really glad people are figuring it out on their own though :)

Not necessary a tutorial, it can just be clearer feedback during gameplay.

If you match bullets, you have bullets flying to the magasin. You match guns and the new gun appear in the corner with a flash, particles etc. You can also put the bullet pattern next to the gun so that the player can associate both of them more easily.

And in a jam, if you don't have time to be fancy, just add text flashing briefly that explains the internal logic of the systems. "New gun acquired" "3 additional bullets" etc.

You are right, I'll try and make things clearer in the next jam :)
