It's a very cool game, sort of like an idle/incremental game. But it was a bit confusing at first. I didn't know I can drag the parts onto the circuit, and I think only some of them can? The yellow boxes can't go on the circuit.
Thanks for the feedback! The dragging is kind of confusing because I didn't add any hints. The sticky notes (assuming that's what you meant by yellow boxes) are upgrades and not draggables.
