Since it's all chance, wouldn't it be possible, in theory, to kill the demon in the first battle? I really doubt it would ever happen, but I just wonder what would happen?
All you people who are saying the game is stupid because the roller coaster falling off the track are taking it too seriously. The game would be really lame if the train sticks to the track the whole time. There would be no way to lose if you made a track, and no matter how crazy it was, it would just follow it around the whole time until it reaches the finish line. And that would make for a really lame game.
put a space between buildings and do not upgrade until you have a building in every other slot. then upgrade all to 2 and fill in half the empty spaces. upgrade all and fill in the last spots. upgrade then. build from right to left.
