Excellent level design with the dimension mechanic :) I'm one of those who struggled to wrap my head around z and c. Beat it in the end! If space bar was jump, my silly gamer brain probably would have beaten it a lot faster ^_^ good job!
My bad hehe, turns out I'm used to play games like Hollow Knight or Celeste on the keyboard so that's why I chose these buttons. Glad you liked it though!
