Since this is the most active of the games-related forums I decided to post here, is this on anyone's radar?

It's called Maximum Roller Coaster, an indie game entrant in the 2012 Independent Games Festival. One look at the shaping in the trailer will make your skin crawl, but the game itself has potential (although it clearly borrows heavily from NL). If nothing else, it's interesting to see another take on a roller coaster design game with a simplified approach to design and slightly more robust gfx engine.
