The game runs at a constant 24.9% cpu usage on my shitty laptop when I first open it and am sitting at the main menu. It drops down to about 8% when "Listening" and once finished it remains at about 1%
I find it rather curious that when it appears to be doing nothing it's using the most resources but when it's displaying digits and playing an audio track it's only using a third as much resources only to then drop down to basically nothing doing what it was before I began listening.
The game outright refused to run when I try to call it via a .BAT file with arguments. I got around this but they still didn't work :(
