This game is an information parser, in a style reminiscent of Papers Please.
It took me several tries to fully figure out the whole setup, and I noticed how the information, both on the machine and in the manual, changed with each attempt. What I struggled with was the "Flashing LED" part of it. I originally thought this meant the LED was simply lit up, but when that didn't seem to work, I went for "Rapid-Blinking LED" which got me there. Best part? My head's not exploding!
There are still many left for me to go through, but I expect this one to rank very highly in Graphics!
