Was that Orphee and Euridyce ?
Certainly inspired by that myth ! I shivered when I figured out the title. However, I was disappointed at the end since the greek myth don't end that way.
If you wanna know, Orphee is a poet that lost his wife at their wedding, she was bitten by a snake. He decides to go after her in the deep hell and since he's very talented with music, he don't meet much obstacles. Then he meet Neptune (which we can compare to the last boss) which is convinced by Orphee to get his wife, Euridyce, back. Neptune agrees, however, he might NOT TURN BACK until they are out of his kingdom (hell). As they were almost reaching earth, Orphee turn back in a doubt if his wife love her, and Eurydice disappear. Orphee then get back to the surface alone in dispair.
Now this game is really good, old-style, those games you know that still make you use your imagination. Get back memories !
Plus, I had no problem with controls like some of the guys seems to have had.
Sorry for my poor english. Great game !
