Earlier this week, the wall-scrolling blaster Scram Kitty and His Buddy on Rails was assigned a March release on the Wii U eShop. However, NintendoLife's exchange with developer Dakko Dakko suggests the platformer isn't due for North America or Europe until April. The above trailer's description on YouTube reflects the April time window as well.
Neither an exact date or price have been announced yet, but considering Scram Kitty was initially shown in an eShop indie sizzle reel in November, just having the release month is a start. April would be a good choice, too - after Donkey Kong Country: Tropical Freeze in February and Watch Dogs sometime this spring, the Wii U's next big release, Mario Kart 8, isn't due until May.
