DogTag Games is the portfolio of Simon René Stempfle, a computer science graduate whose studies focused on media. The site presents a varied collection of games, prototypes, and an animated film, highlighting projects across different genres and platforms. Visitors can explore Mooney Island, an open-world game set on an island, and Color Catcher, a mobile game centered on matching colors. Other projects include Snake 3D, a small C++ and OpenGL game; Block Game, a prototype; and Piano – Education in VR, a serious game designed to teach piano playing in virtual reality.

The portfolio also features Prüfungsjagd, a first-person adventure about a university student, and IShipIt, a Battleships game playable locally against a bot or in multiplayer with friends. The Revenge of the Fly series includes the original game, a remake in which flies take revenge on spiders, and an animated film connected to the games. Together, these projects offer an overview of Stempfle’s creative work in game development and interactive media.
