I have just finished building my very first parkour ever! I call it The Tinker Course, and it gets the name because the parkour can be located in the arctic side of Tinkerworld (overworld). So if you ever have any spare time on your hands maybe you can try it out!
UPDATE: Loads of people have complained about the checkpoint and the fact that there is not enough, SO, I have added a brand new checkpoint, now making that 2 checkpoints in the whole course. The new checkpoint can be found after the wood stick part, and i feel that is pretty fair. Possibly i will add more checkpoints in the future only if i get more complains again.
One last thing. People are getting mad over the fact that i buffed the course but when i made this course, i wanted it to be very hard but when i finnished making it, it just wasnt as hard as i wanted. I wanted a course that could take hours for me to complete. I didnt want an easy course that i could beat in seconds and just forget about. So im sorry if you dont like my creation, but i promise when i get the money for a new course, it wont be as hard as this one. Thanks for understanding and wear a seatbelt. (I just found out i could edit a discussion)
