Good idea, and well presented! Lots of content too.
Feels like the difficulty slider is back to front! I turned it right down to 15 (most games jam games are way too hard) because I thought that would be the easiest setting. Actually realised that it was the length of time between ident check in before failure.
Would have loved a mouse invert option. It was practically unplayable for me under pressure. I'm so used to inverted controls, I typically have a really hard time in games where they are the standard way round. Especially games like this, where you have to move fast and accurately. Hard to do when you're always finding youself staring at the floor or ceiling!
