The game rating (+18) was odd and I kept myself on my toes just in case it would throw a jumpscare or something NSFW at me. I ended up not seeing anything particularly egregious, but maybe there is some secret part which is more intense.

Nevertheless, this is a cool idea, and would have enjoyed seeing it expanded and fine-tuned further, eventually with configurable speeds and a way to start over.

Something different from all the platformers etc. For somebody with adhd quite hard since the speed of the information is pretty high. Maybe you could consider adding different speeds or make the player adjust the speed to some extend. Overall a cool idea.
(The typing sound is indeed very nice.)
