It seems users either really like this piece, or really don't. I myself am in the first category.
Story is sometimes difficult to communicate in games, particularly in games with such low-bit graphics and minimal set pieces. However, unlike many mainstream platforming vehicles (Mario, Mega Man, Sonic, etc.), this entire experience seems to BE the story, rather than simply progressing it, and I find that extremely satisfying.
Every little thing in this game seemed to mean something. From the simple reds and blacks of the background palette, we can deduce that we're dealing with death and the afterlife. From the challenging platforming, we can deduce the hardships our traveler must have faced on his way to reach his goal. From the stirring and minimal music cues and sound effects, we can deduce that the situation is just as unsettling for our traveler as is it for us as a player. And finally, from the ending, we can deduce that the author has a very active imagination.
The controls handle well, never feeling as if they get in the way of the narrative, and the quick "death" wipe lets you know you've screwed up without seriously harming the flow. Also, the fact that your avatar can't actually die makes it a game anyone with enough patience and interest can finish.
And there's a lot of interesting stuff here.
Bravissimo, sir. Easily my favorite recent thing on Newgrounds since "Closure." I'd like to see more dark, unique, story-driven experiences like these.
