I developed a small Unity 3D puzzle game featuring two robot characters that can swap player control. One acts as the active player, while the other mirrors movements as a "clone". As my first project, I focused on basic platforming gameplay mechanics (jumping/pushing) and UI management.

Challenge	Solution
Player Switching System Switching caused both players to teleport forwards or made UI not update correctly.	Built a PlayerManager script to control active/inactive states, camera focus, and UI. Enabled/disabled input on switch.
Character Mirroring Inactive character jittered or desynced from active player.	Updated CloneController script that mirrors displacement and rotation frame-by-frame using Rigidbody physics, preventing snapping/teleporting.
Ground & Collision Detection Players sometimes floated or failed to reset states.	Used OnCollisionEnter to detect grounded states, ensuring consistent platforming mechanics.
Box Interaction Switching while pushing boxes caused unwanted force launches.	Controlled Rigidbody constraints during collisions and adjusted logic to release/lock object movement safely.
Scene Management Needed handling for falling out of the map and level completion.	Added fall detection that reloads current scene on drop and scene index checks to quit game if no next level exists (freezing at the end of level 3).
