After completing a small Unity platformer prototype I had the opportunity to watch Adam, Jordan and some second years play the prototype. These were the main takeaways:

• A lot of them weren’t really familiar with playing a 2D platformer game on a keyboard and mouse
  • I should add controller compatability
  • I should add a way to change the controls to whatever the player wants
    
• This level was way too difficult
  • In the actual game, the difficulty will definitely start much slower and then ramp up
  • I should implement more ‘save points’ where the player can stand and digest what the level requires of them and respawn if they die
    
• Having the grapple and parry jump buttons on the mouse is misleading, it makes it feel like the grapple can be aimed with the mouse
  • Explain to the player that the grapple works in the direction the player character is facing, not where the mouse is facing
    
• However, I was told that the overall movement of the game felt good to play – it was responsive and immediate – exactly what I was going for with this prototype
