Wallwalkers is a prototype that is simultaneously a top-down adventure game and a 2D platformer. 2 players control characters with different gravities and cooperate to explore areas and defeat enemies. The game has 2D gameplay on a 3D map, and has moments where the camera perspective changes to allow players to control their character in a different way.
For Wallwalkers, I created my own 2D asset library. I also learned important skills in Unity such as rotating objects smoothly, restricting and allowing axes of movement, using raycasts for environmental interactions, and triggering audio events.
