Game Design Feedback

[Science Educator]

I googled "studying game design" and came up with this group. Here's
what I'm looking for.

I run a small educational software that has produced the Award-winning
SpellingCity.com website. Our strategy was to have simple focused
games. We've now created a more ambitious game and I'm looking for
some feedback from experienced game designers. Could you post an
invite for people to come give us feedback?

It's a pretty simple Flash game whose main value is that the students
can play it with their own spelling list (like the other ten games on
SpellingCity.com).

Latest version of the game: http://www.spellingcity.com/components/com_spellcity/games/tests/LetterFall.0.1.5.html
