Forgotten (Free) Gems - Today: ETERNAL DAUGHTER

I'm amazed that this game it's not popular.

I borrow this review from hardcoregaming

Eternal Daughter - Windows (2002)

There are many indie platformers more well known than Eternal Daughter - and that's a real shame because there aren't many indie platformers as good as Eternal Daughter. Despite its relative popularity in the early 2000s (a few years before independently made games caught the attention of mainstream audiences), the game is mostly forgotten nowadays. What could have been the American equivalent of Cave Story (in fact, Eternal Daughter shares a few similarities with Studio Pixel's masterpiece) has instead faded into obscurity. While one of its creators, Derek Yu, later went on to make Aquaria and Spelunky, his best game remains severely underappreciated.

It's hard to tell why this game became so obscure. It might be because of its high difficulty or some of the issues one can encounter while playing it on a modern computer (caused by its 320x240 resolution that is unsupported by many video cards as well as the limitations of Multimedia Fusion engine in which it was programmed), but it might as well be that the game was simply released a few years too early. While today a beautifully animated retro metroidvania with a female protagonist sounds like a recipe for indie game success, such games weren't that popular in 2002.
