Mario Clock

Mario Clock is a DSiWare clock application released in Japan on April 1, in North America on June 15, and in Europe and Australia on July 3, 2009 for 200 DSi Points. This can also be downloadable on the Nintendo 3DS' eShop for US $1.99. The alarms can be set to be Mario-related sounds. The clock can either be set to analog, or digital.

There is a small easter egg in the game, which allows the player to jump (whether they're using Mario or Luigi) and collect coins, after every 100 coins, one of the Mario Brothers swaps out with another one, allowing the other brother to collect another 100 coins, and so on. If the analog clock is set, every 100 coins collected, a sprite of Mario or Luigi will appear over one of the numbers starting from 1. When 1,200 coins are collected, the player will arrive at World 8-4, with Princess Peach waiting on one of the brothers. She will thank them, and introduce them to another quest.

The player must also collect Super Mushrooms and avoid Poison Mushrooms. The stage changes for every 15 minutes that pass in real time, with a castle appearing at every hour.

''Turn back time and enjoy a bit of classic game play based on the original Super Mario Bros. with Mario Clock. Help Mario and Luigi collect more coins than ever (POW block anyone?) while they run through a variety of stages. Gather enough coins and you'll be treated to another scene bound to bring back fond memories for many. Mario Clock includes both analog and digital clocks that use the system's internal clock or allow you to offset the time however you like. Program up to three alarms (with snooze functionality for those that need it) and assign them a Mario-related sound or use one created in the Nintendo DSi™ Sound application. You'll find yourself thinking "Just a few more coins..." in no time!''

''With Mario Clock, you'll always have the time wherever you go! Wake up with classic Mario music, or simply use the Nintendo DSi system as a desktop clock complete with a Super Mario Bros. background. You can even make Mario jump, bash blocks and collect coins!''

Customise the clock to your liking: choose from analog or digital displays, 12-hour or 24-hour modes, and set up to three separate alarms with different NES-style Mario tunes or use your own saved sounds from the Nintendo DSi Sound application.
