Are you a fan of Whale Trail? Would you like your kids to play it too, sans in-app purchases and advanced mechanics? Then you and your kids will definitely enjoy Whale Trail Junior.

Whale Trail Junior is a more child-friendly version of the popular endless flyer, which my colleague Christine described as “delightfully colorful and addictive” in her review last year.

Released just a few hours ago in the App Store, Whale Trail Junior is aimed at little players between ages 3 and 6.

As mentioned, unlike Whale Trail, Whale Trail Junior neither offers in-app purchases nor challenges players with advanced mechanics.

Of course, the Tiny Wings-like one-touch control scheme is retained in Whale Trail Junior. Touching the screen anywhere still makes the main game character, Willow, fly in the rainbow-colored sky. But a virtual button is also provided to serve as a persistent visual cue for kids.

The premise of the game is simple. Players just need to collect the five stars in every zone to activate frenzy mode, in which they’re free to bust the unfriendly Thunder Bros.

They don’t even need to collect “blubbles” to keep Willow’s trail going. Also, they don’t even need to keep Willow flying. Willow just coasts along the bottom of the screen and doesn’t fall to his death (gasp!) when his flight is not maintained. Which is just as well for the little ones, right?

As they play, kids gets to unlock the game’s nine zones and 12 characters and costumes.

The zones are: Red, Orange, Yellow, Green, Blue, Indigo, Violet, Party, and Storm. And the characters and costumes are: Willow, Wagner, Stripey, Emmy, Sailor, Wendy, Yeti, Knight, Ninja, Robot, Space, and Chief.

Compatible with iPhone, iPod touch, and iPad, Whale Trail is available now in the App Store for free. The original Whale Trail is, of course, still available, also for free.
