I'm so glad someone's mentioned CrossCode! Such a wonderful experience from beginning to end. The world really feels alive with every inch of a mal being used to either enhance the story or hide a puzzle! I loved seeing chests and figuring out how to get to them across several maps.
I'm really looking forward to their next project, Alabaster Dawn. I hope it's just as good!
No they're wrong in mathematics too. -5^2 is -25, but -5^2 is not the same as x^2 where x= -5. No brackets needed on x.
