Many of Jin's maps begin by changing values in the editor to an extreme degree, which results in the discovery of new concepts and glitches in the map editor - he is known for innovative and unique mechanics that he has created in this fashion. A frequent colour palette for his maps uses blue-green for the background and green for the basic colour of platforms. You should recognize the difference between making an original map and making a remix map. WeiRd DeAth BalL is a remix of "Deathball" by Botnick but it also has some unique gameplay which makes Jin's version subjectively better in many ways.

This map is a remix of the map "Deathball" by Botnick but posseses a unique gameplay of being able to grapple the floor for a boost and also being able to do more tricks thanks to the Follows path joints.
