Map Info:
17 is a parkour-map with a bit of puzzle included. There are 17 levels, like 'find the button', 'parkour', and one, with fighting mobs.

There are also 11 different colored special blocks with their own effects:

Stained clays
Cyan: Slowness
Yellow: Poison
Lime: Jump boost
Light Blue: Swiftness
Black: Blindness
Purple: Nausea
Orange: Fire Resistance
Red: Death
Other blocks
Lapis Lazuli: Water Breathing
Obsidian: Clears Effects
Gold: Sets Spawnpoint

(This may seem a lot of different effects and hard do remember, but it's not)

I made a playthrough of this map, so if you're stuck, you can watch it: 17 - Playthrough
