Muscle Man now on Wii Shop Channel

As is the custom of a Friday, a bundle of new downloadable games are being released today for the Wii and DSi.

Topping the bill is Muscle March, a bodybuilding-themed game which could only have come out of Japan. It's all about striking a pose and winning protein powder, apparently. Plus, "Muscle March will also be the first WiiWare title to offer a polar bear in a Speedo," says the press release. Yours for 500 Wii Points (£3.50).

Popping up on the Virtual Console is Milon's Secret Castle, an old NES game which involves an evil warlord, an imprisoned queen and some magical balls. Expect secret items, fierce enemies, handy shops and bonus levels, too. This one comes in at 600 Points (£4.20).

Retro fans may also enjoy Castlevania Rondo of Blood, the tenth instalment in Konami's popular series. You play as Richter, who comes complete with Vampire Killer whip, and must play through 13 stages. Highlights include "CD-quality game music". At 900 Points (£6.30), it's cheaper than an actual CD.

This week's additions to the DSiWare store include Photo Dojo (200 Points / £1.40). Photograph yourself doing various punches, kicks, special moves and poses, then record your voice to add sound effects and take a picture for the backdrop. Next thing you know you've created your very own fighting game. You can battle AI enemies or get a mate to take photos of themselves, and fight each other on the same DSi.

Then there's Flips: The Enchanted Woods, an interactive version of Enid Blyton's classic tale. Follow the adventures of Joe, Beth and Frannie as they visit the Magic Faraway Tree and meet Moon-Face, Silky the fairy and Saucepan Man. Together they will solve the mystery of who has been cutting up the prostitutes and putting them in the canal no sorry that's Flips: Wire in the Blood. This one costs 500 Points (£3.50).

Those who prefer actual games to interactive children's books may enjoy Libera Wing (800 Points / £5.60). This tower defence title sees you playing through 36 story and 24 quick-play levels, using items and commanding ships in some sort of strategic fashion.

Or how about Car Jack Streets? This is an action game with a bit of driving and a lot of crime. Turns out you owe the Mob a million bucks, and they want it now. The only way to pay off your debt is to rise up through the criminal underworld, presumably doing a lot of driving and shooting along the way. It costs 800 Wii Points / £5.60 (or £1.79 on iTunes, but don't say we sent you).

And finally there's Flashlight (200 Points / £1.40), which turns your DSi into a torch. "Flashlight will also be helpful if you are stranded. You can use the warning light if your car breaks down and the S.O.S. function will come in handy if you ever get stranded on a deserted island." If only Jack and Kate had packed their DSis.
