Sixteen percent of Nintendo's stocks have dropped five days after "Super Mario Run" was released. Analysts blame the lukewarm reviews of its newest game.

The "Super Mario Run" is Nintendo's first full venture into mobile gaming. It marked a significant shift for the firm which focused solely on making games for its consoles. The game is only available iOS and it's currently having an average rating of 2.5 stars in the Apple App Store.

Early reviews and sales of the "Super Mario Run" disappoints investors. The Nintendo shares down 7.1 percent in Tokyo Stock Exchange trading. During the five day streak, the stock has fallen more than 16 percent. The Nintendo stock had risen more than 20 percent in a month before the slide began.

According to the Wall Street Journal report, Nintendo's share price has taken a hit for five consecutive days. Analysts says that despite the pre-release hype surrounding the game, which in fact spiked Nintendo shares as investors went all in on the game, negative reviews post-release were a major point of concern.

Polygon reports the other big concern of investors in "Super Mario Run" is the $9.99 price point. Unlike "Pokémon Go," Niantic is very successful in its mobile game that was released last summer for free.

The Nintendo investors were also concerned at the lack of new content the developer bring to "Super Mario Run." The game was launched on December 15, 2016 and it is the top game downloaded on the App Store in North America, but it has experienced an opposite fate in Japan.

Many players criticized the "Super Mario Run" game. Some say it was too expensive compared to other titles and games in the App store. The first three levels of the game are free, but the full game costs $10 to play.

Despite the current issue of the "Super Mario Run," Nintendo confirmed the game will be coming to Android devices in 2017. No exact release date when Android users will be able to play the game, but Nintendo may announce this first quarter next year.
