A day -1 patch removes a prominent complaint.
A patch will be available for Super Mario Maker that removes a source of frustration about the game.
The version 1.01 patch is available for the game's release in Japan and Western gamers who got the game early, and includes the following bullet point: "Condition(s) for increasing the amount of usable parts (in the level editor) were added." The patch's actual effect changes the unlocking of parts from the next calendar day to shortly after an undetermined amount of building material is used.
Nintendo World Report will be investigating the new unlock system and will update our review coverage as necessary.
UPDATE: According to user feedback, it appears the "15 minutes" timing refers to how long it would take to use a certain amount of the building materials in a level. Nintendo is hosting a Twitch stream at 3 p.m. Pacific, and we hope for clarification from the Treehouse at that time.
