So, I've gotten to floor 2(11 for some reason) and the game seems to be asking me to change the value stored in a particular register to 01010101. My only options for interaction with it seems to wipe the contents of the register. I assume there's something I'm missing, but I can't work out what as the game doesn't make it terribly clear, as far as I can tell....

Hello, can someone explain what the different puzzle elements actually do? 1. What does "Latch" do? (And, if possible, which floor teaches players what it does?) 2. What does "Shift" do? (And, if possible, which floor teaches players what it does?) 3. What does the "Loop" circuit do? There are two buttons with non-discernible function....

In this image: https://steamproxy.net/sharedfiles/filedetails/?id=2366640365 to solve the puzzle, input 1 needs to be on, and input 2 needs to be off. But they're literally connected, making that impossible. What am I missing?

I'm now in the huge room of left-half part of analog level where I need to make waves I need to turn on the switches. I've tried many times but failed to solve the puzzle which I need to make three peaks, the left of which is weaker than others. Now I meet the problem that the horizontal position of the right peak of the destination wave is a bit different from that generated from wave generator, the latter of which is more close to the right edge of oscilloscope, and I don't know how to make it correspond...

I've finished what I think is the first level, the 8 floors of an elevator.. but now I don't know where to continue lol
