I have been doing game development for a few years, mostly in Unity (both 3D and 2D) using C#. A few of these are showcased here. My Itch page also has some games public, mostly ones made for gamejams.
An aquatic exploration game where you play as a marine scientist who's submarine has malfunctioned, and is rapidly dropping into the depths of the sea.
A first-person shooter game where you unlock abilities after each wave.
A mysterious experience in a hospital room full of interactable objects, set on the edge of a cliff that drops on into...??? (made in 48 hours for Kiwijam 2020)
A Papers Please-style game where you convict war criminals at the United Nations, but everyone's a horse (made in 72 hours for Ludum Dare 49)
A pretty shit, very simple top-down shooter game against waves of enemies.
