(Off topic comment) With the font you're using to write code it's sometimes difficult to read some of the characters. For instance, I had some problems to read the `getKey` method, since the `K` char is pretty blurred.
It's supposed to look like an old typewriter with partly broken types, but it looks like they overdid it on the "K"... plus no typewriter I know of can write with light color on a dark background, so that kind of breaks the illusion.
I came to write the same thing. Fine for reading text, not ideal for code
The K character is completely invisible on my machine even
