Really beautiful environments. You have put a ton of work into all the atmospheric stuff--fog, rain, water, waving grass, as well as the fonts and the really lovely music. The map is large, but I didn't mind because it was so clearly meant to be wandered around in (and because you helpfully included so many navigational aids, much appreciated).
The keybinding problem really is something you should pop in and fix though--it would only take a few minutes!
