I did it :O I just S-ranked the game:
Also, some of screenshots of the hardest achievements:
The Speedlunky achievement was intense. I dug a hole and had no rope to get out, so I jumped on top of a monkey and boosted my way out of the hole.
The $0 achievement can get pretty nasty, particularly when gold can hide in trees, snow, and behind columns.
Anyway, post here if you've gotten a Spelunky S-Rank or if you have questions about any of the achievements.
