What kind of games? To start with you can draw on your learnings from Block One - from Swift Explorations and Swift Fundamentals - a personality test to decide what pastry you are, or instead of Rock, Paper, Scissors - Danish, Toad, Apple? Or sticker/social image app. I'm not just assessing you on the complexity of your game, but all the designing, testing and launching too. You could also make use of your learnings from Coding Two - using all the game knowledge to make a
Frogger clone (Toader?). Or your learnings from this unit - what kind of playful AR experiences could you make?
