Really fun idea, and clean execution! This really made me feel for my EE friends who have to do this but with integrals 😅. I think it made sense that you couldn't move the components after they were welded in, but it made me restart really often, when i could have just tried reconnecting the electricty. I think I got past the final level without really understanding the red/blue battery mechanics? since, often there existed a charge on the red/blue batteries when my other batteries weren't even connected. Overall, liked it, and esp like the little faces on the resistors.
