Ugh - I was so worried about this. I almost cut Jumping solely so that there would be one less button on the tutorial. I also thought about having a little fade-in pop-up in the lower right corner that would remind you of the main controls each time you died. But then I worried that that might interfere with the aesthetic / immersion, in addition to making some players feel like... patronized? Yaknow?
What do you think? How could I have handled it better?
