This is a very slow start game, but it does pick up and get fun! I think the main issue is that watching the rollercoasters get to the end doesn't really have you do much, which is especially boring at the beginning, with you just clicking a button and, on top of that having to wait between each time you do it. I think watching the rollercoaster is the best part of the game (eventually), though, seeing the little guys fly out, I think it just needs more interaction. Maybe you could click on the little guys to catch them and save them or something and the rollercoaster starts automatically, I dunno. I stopped when I think I had too many carts and the start rollercoaster button stopped working, but I had fun!
