I find the font colour problematic at times, because it's very similar to that of the opponents; so occasionally a selected word isn't easily visible against it's background, and I'm not certain which letter I've missed.
Also, thanks for a surprisingly entertaining, and maybe even useful game :)
yes it would be great to avoid the words to overlap. And also when I begin to type in a word I cannot switch to another target, I must finish the current one. It is ok! But could you make the current bigger and red instead of orange please? :-)
