Orkybash, the word you're looking for is pensive. I don't know this game, so I don't know if this is the mood the game is supposed to evoke. Then again, I love LousySpy's "Blue Vacation," which is a bastardization of the bleeding-edge guitar-wailing love of F-Zero, so I can't say this would be much of an impediment for me.
Anyways, yes, this song is all suspense, no climax. I don't see that as a problem. What this song does, it does damn well. Whether or not you like what it does is up to you. As for me, I'll chalk up another one for Malcos.
