Pitfall styled graphics coupled with SFX out of Rosemary's Baby against a backdrop of Orpheus descending into hell, and great music. The gameplay is pure timing and spatial manipulation, there's an interesting cognitive dissonance when you play and the viscerally simple mono-blot of hell, gamed out with 8-bit charisma, contrasts with a stark sense of ambiance.
What we would have here is a highly stylized, well executed throwback to the good old days before I was born - but there's something wrong. The title does not come from the running obstacle course so much as the twist at the end. All the Megaman level challenges, the horrors and retries, they amount to something not quite so pat and cliched as the usual end-of-level macguffins. In the original story of Orpheus he betrays the rule against looking back, his pre-occupation with the wife he leads out of hell keeps her away. In this version, you deal with Metroid-style circuit design on the way out where your constraint becomes moving forward without looking back. It's a good use of gameplay to tell a story, but in an existential inevitability, like the situation in Pazzon, you'll end up losing her anyway, and then you'll blink and wonder if you're playing Braid. And it'll be cool.
Tobin wrote a good review of this as well, and he seems to think there's something uplifting in the ending. I think there are at least two interpretations. One is that the inevitability of the gameplay's linear flow mimics the inevitability of death, but if we move forward without regret and enjoy the trip through hell, then that's cricket. The other is that the whole thing is just a thought loop, which it is in your brain rather than the characters (except to the extent you ware the character - whoa!). The man is staring at his wife's grave full of regret, digs deep into himself to find her amidst a hell of self-doubt and second-attempts, and then in the recovery finds his own peace.
The real question is, can a platform game with cheap graphics and a clever aesthetic really call us to question our attitudes about life, or am I way over-analyzing this? We know a maze game can. There's nothing left to do but play your way to a resting place in the heart of the world.
