Dr. Robotnik's Ring Racers - Lightning Cup (Master, Rena Ryuugu)

Mario Land 2 Wario came out of nowhere near the end holy fuck. Otherwise not much really changes in terms of difficulty spots. Nova Shrine I'm not great at but CPUs like falling off.
Rena here was made by Chengi and uses Sakura's statblock of 4 Weight and 5 Speed. Chengi does great spritework IMO and was responsible for quite a few of the basegame characters.
