Feels a lot like Canabalt, down to the music. These kind of games are not my cup of tea, but even considering that, i only played more than 2 times because of the card. Its well made, but more effort should have gone into making it stand out from Canabalt.
Also, i know talking about "realism" in a game is rarely relevant, but anyone with some basic understanding of physics will probably reel at the thought of a roller coaster car jumping on rail platforms -_-
