few things could be improved
first of all a FREE PLAY mode is needed so you can draw your own coaster both for fun and for practice. It also needs a revamp on the thrill meter because jumping a gapt from track to track should give some kinda thrill. also if you fail the track you should have an option to keep the coaster instead of having to draw a new one. a option to adjust sound in game is also needed. it was a great game keep it up
