Breaking news! The park is having a water coaster and a Motor Coaster!!!
Right now I guess the water coaster would be similar to Divertical at Mirabilandia (probably a clone). The park mentioned about it using elevator lift with two sets of lift track, being 40m tall (around 131ft), having maximum speed at 100kmph (around 62mph) and its maximum drop angle is 45 degrees. They also mentioned it would be a mixture of rapid ride, super splash and roller coaster.
The Motor Coaster would reach a maximum speed at 63kmph (around 39mph) within 2 seconds using fly wheel launch. I'm picturing a Zamperla Motor Coaster or some kind of Chinese knock-off.
