Super cool concept, pretty fun to play. I included it in my AGDG Halloween Game Jam compilation video series, if you'd like to check it out :) https://youtu.be/1vbKEuv0cCY
the numbers on the crafting screen are corresponding to the number keys, and that's which trap you have 'equipped.' So with a holy cross crafted, you hit 4 to equip it and F to place it as a trap.
