Tengami developer Nyamyam has confirmed it has delayed its colourful Japanese pop-up book game on Wii U, iOS, Mac and PC.
Nintendo Life reports that while the game was originally slated for a summer release on iOS - with the other three formats to follow afterwards - the game has been pushed back on all platforms to a blanket 2013 release window.
In a statement, the studio's co-founder Jennifer Schneidereit said, "In some interviews earlier this year I said that we were hoping to release Tengami this August and we stated on the website for a long time that a release is planned for the summer.
"While Tengami is definitely coming out this year we still have a fair amount of work to do and therefore we won’t be releasing this summer. We are sorry for making you wait so long, but we have spent almost 3 years on Tengami now and want to keep working on it until we feel it is ready.
"Tengami is still coming out on iOS first and shortly after on Wii U, PC and Mac. More platforms are possible, but we have our hands full with these four for now.
"Phil is doing some initial work on Tengami’s Wii U version, while Ryo and I are finishing off the ocean level. After that we want to make one more level, which will make for a total of three levels in the final game."
