Hey there, cool map but I do have some technical problems that you have to address. It seems that you've made this map in the latest version, but the issue is that manacube parkour is for 1.8. The 2 versions have some technical differences that make some of your jumps impossible in 1.8, which is not allowed.
To begin, in 1.8 you cannot jump 1.25 blocks high, so all these jumps are impossible due to that. The head is 0.75 blocks, and the iron bar is 1 tall, making a total elevation of 1.25.
Another case is with this jump here (pane to flower pot). In 1.8 panes are 1 pixel shorter. While this may not seem like much, in this case it actually makes a massive difference, with the extra pixel allowing you to gain more speed. This makes this jump insanely hard, maybe impossible in 1.8.
Furthermore, 1.8 water physics are also different. In your particular case, it makes this jump impossible in 1.8.
You will see what I mean if you attempt your level in 1.8.
I hope this helps.
