Hexiled looks great! The graphics definitely stand out (especially the space theme). I'll play it tonight. Best of luck.
I do think the OP's apps look a little too much like Letterpress. If I had seen them in the App Store, I would have dismissed them as a ripoff and have never given them a chance...
Also, the font in the Letters app doesn't look as professional as Hexiled, Letterpress, or SpellTower. Even in the app icon, the letter L's font weight varies, and the 2 feels italicized in a weird way. See: http://i.imgur.com/MV2SAQK.jpg
It's funny you should say that as the font in Hexiled ended up being the very, very default Arial Black and the icons are almost entirely based off Font Awesome. I paid a lot of attention though to consistency where possible (colours, use of caps, "voice" of the game, etc) but there's a lot of room for improvement.
Thanks so much for the encouragement. We've had a great experience launching the game. I'm on Twitter at @isaacforman if you have any feedback about Hexiled.
Nothing wrong with default fonts... :-) I've used many an app that uses nothing more than Helvetica (Neue).
Maybe it's just taste, but I found Letters' font to be too rounded. It's like Arial Rounded, and reminds me of Comic Sans. Letterpress's font is also a little rounded, but for some reason it looks more professional to me than Letters' font.
