I suggest you guy to increase the train (roller coaster) length to 15 ,and i suggest you guys to let us add some part to custom your coaster,you can insert text or decal in it,so you can make a safety reminder on your ride seat(this can make the game more realistic and customable),last suggestion,i suggest you guys make a new coaster (Search the ride called Wicked Twister) i suggest you guys to make this coaster.
(These update suggest can definity make you game more popular)
Or developer can just make it into inverted coaster new credit skin
