This is clever! A few notes:
- I could've used the ability to zoom out further: I'd get a new route, and spend time trying to even find them on the map.
- I had a real vowel problem: There were a lot of times when I had no vowels; there's always the delete option, but that loses you tiles, and I'm not sure I got any vowels at all in my last fifteen letters (which made it really hard to get new tiles).
