I LOVE IT 
The blocks all work together so well and it would be a nice change from the current nether themed one!
Feedback: you could try adding more random holes around the lower platforms to make the user more careful, the obstacles currently seem quite symmetrical and so adding randomised holes/obstacles may make footing less predictable (and more fun!)
i forgot how to english, so if anything doesnt make sense let me know :)
Keep up the amazing work!
edit: also the drive links dont work
