no my input works otherwise. I tried restarting your game a few times and around the 3d to 4th room things stop working for me. Its like its having trouble getting input from my controllers. I play someone else's game after and it worked just fine.
If I go to room 3 and connect and unconnect a bunch of items, also select and deselect by selecting the object again. Eventually 15-20 seconds the connector stops working. I recorded a video after it broke. https://we.tl/t-OyHynikLwt
