Despite the announcement of the upcoming Switch Lite was made very recently, we're nearing its release already and the even more portable version of Nintendo's hybrid console could be getting content or features in Monster Boy specifically created for Monster Boy and the Cursed Kingdom.
This rumour (and yes, it is a rumour considering nothing's been announced) comes from the official FDG Entertainment Twitter account, where they state the following: "We have a fun idea for Monster Boy running on #NintendoSwitchLite - it's a nifty feature that Nobody needs but it has to be done! Patch 1.0.5 is in the works".
The feature is not needed, but it'll be interesting to see what the feature actually is.
