A Stumbling Through suggestion for David.

KAVALMAJA - A retro-looking, Zelda-style metroidvania game done in true NES-style "no tutorials of any sort, you're on your own for figuring stuff out" fashion (translation: NO OMACHAO). I first played it years ago, and while it gets a little irritating at some points, I love it.

I'd have suggested it years ago, but I could never quite remember the name.
