Here are some samples of work that I've done with Unity and C#.
This is from a simple rolling-ball game I made where you have to collect pickups that let you temporarily boost your speed as you try not to fall off the map.
This is from a digital version of a card game I play with my family called Rat-A-Tat-Cat. It was my first attempt at programming a card game, and it taught me a lot.
This is from a lighthearted arcade game I was the lead programmer on with my IU Game Design Workshop team. In the game, you play as a hero called AllerJack who has super-sneeze abilities, and you try to defend the town from falling meteors by sneezing them away.
