Yes, only the first five rooms are modified, the remaining 15 are the same as in the original "Manic Miner". It is controversial whether this 'product' should be considered a new game. That's why on the title screen I called it 'Craig Rothwell's modification of five rooms in Matthew Smith's "Manic Miner" ' rather than 'a game by Craig Rothwell'. However, Craig did create a truly modified game later on, for the DOS platform. Please see web.archive.org/web/20011015023227/www.cdworld.co.uk/craig/jsmw.html for more info.
