Minecraft Ninja Warrior/Sasuke

I have recreated Ninja Warrior in Minecraft! Originally known as Sasuke (It's Japanese), 100 athletes try an intense obstacle coarse, consisting of four stages. Only three men have ever completed all four. Now you can try, right at your computer.

Features:
- A scoreboard timer that goes by the tenth of a second
-8/22/13 A first stage with five obstacles, to weed out lower class competitors
-8/22/13 A rope swing to sample so I can implement it in later stages

Some rules:
-Complete each stage by making it to the end without running out of time, or falling into the water (void).
-8/22/13 Stay back from the pressure plates while one person is running; the redstone can't handle multiple people at once yet, I tried

Do leave any feedback in the comments to help my map improve. Yes, I have seen there are Ninja Warrior maps, but my map goes for the skills to do an obstacle rather then the look of it. Thanks for reading.

Note- Aesthetics are coming!
