The devs and publisher aren't lying, this game does support KB+M on every console it was released on, even on the Switch 2 (external mice don't work for it btw)!
Definitely more violent than DD: Born Again, and the most violent MCU project ever made. Hopefully something like this is also gonna be made for theaters.
What is the age rating for it in your country?
I just noticed that for the "Beat It" segment of the movie, Jaafar wears the exact same shirt that "Weird Al" Yankovic wears in the coverage take video for his "Beat It" parody song ("Eat It"). Very interesting detail there.
This is just the demo btw. I just wish I bought the physical version with the SonarPen when it was still easily available several years ago :c
