Last Friday, Nintendo announced the launch of a spoof double-playing game called "Stretcher Block" in the state of zero announcement. According to recent data mining, the game may have been completed six months ago.
According to the discovery of data mining enthusiast SimonTime, the 1.0.0 version of this work has been uploaded to the Nintendo server as early as May 29th. From the time schedule, it is likely to be prepared for E3. But I don’t know why the reason was delayed for half a year before I officially met with you.
(Before the "Fitness Ring Adventure" and "Brain Exercise" new work is also staggered E3 and September two times will be announced separately, I do not know how many such games are waiting to be released in Nintendo)
