Wasteland Courier is a post-apocalyptic VR cycling game controlled by a real indoor bicycle trainer. Instead of a traditional controller, the player rides a physical bike, with pedaling, steering, and physical effort directly mapped to the virtual environment. The project was part of IMI Showtime 2025/26, where our team presented the game at a public exhibition with a dedicated booth, trailer, and live demo setup.

My contributions:

• Project management and coordination within a 5-person team
• VR setup and hardware integration in Unity
• Gyroscope-based handlebar steering implementation
• Bluetooth communication with the bike trainer
• Player movement and reward systems

Expedition Survivor is a first-person multiplayer tower defense and exploration game inspired by cooperative survival titles. The game was developed in a two-person team and is still in active development.

My contributions:

• Multiplayer setup and synchronization using Unity Netcode for GameObjects
• Networked player movement
• Item and object placement systems
• Enemy behavior and combat interactions
• Health and reviving mechanics

Astro Dog is a first-person exploration and collection game created as part of a scientific university study. The goal of the study was to investigate how the autonomy of a companion character influences the player’s parasocial bond.

Two variants of the companion were developed, differing in their level of autonomous behavior.

My contributions:

• Companion AI using Unity Behavior Trees
• Core gameplay systems (movement, item interaction, companion interaction)
• World creation and level layout
• Implementation of study-specific gameplay variations

Shared Body is a cooperative puzzle game combining a physical card game with a tablet-based digital game. Players use real action cards (e.g. move, jump) that are scanned via QR codes using the tablet camera to control a shared character.

The game focuses on timing, and implicit coordination between players.

My contributions:

• Initial game design concept
• QR code scanning and input handling
• State-machine-based player movement system
• Integration of physical card input into digital gameplay
