I got that, but why do I need to press up & right to go down & right (or up/left, I forget which)? Either both directions should be flipped or neither; they're inconsistent as it stands.
Nice little experiment that clearly communicates what it's doing. It's neat to see when sometimes I can tell what word will be typed, and sometimes I can't. Would love to see this extended into a more extended game - you could do some interesting things with it.
