As a non-expert reading this thread with some objective distance, the repeated recommendations that stand out are the importance of a distinctive (& searchable) name, and a graphical look/description that fights 'copycat' impressions. (Otherwise, the game never even gets a look from players or reviewers.) So maybe fresh eyes & new language/visual brainstorming would be more relevant than a financier?

You've already got one possible alternate name – "The Letters Game" – in your domain/twitter-handle, but I suspect something even more distinctive is possible. You might also tweak the icon and color scheme to convey more novelty compared to the famous category-leaders...

Well, a publisher or submitting to the major mobile gaming sites, like TouchArcade.

Speaking of, have you made any threads in the Touch Arcade forums? I've seen several apps get their initial exposure by just posting and asking for feedback.
