Build: You did a great job with the build, well done.
Jumps: Jumps are more than regular block jumps, and this is a good thing, the only thing is that in some parts jumps are repetitive, and there are some floating jumps.
Difficulty: The difficulty, the map is a hard course.
Conclusion: I am giving a -0.1 (just for the jumps), but if you change that I will instantly change it to a +1
