Note

Unfinished. Roboy is a playable alpha, and development has been on hold since 2023, with plans to pick it back up. What's below is what works today.

✨ Features

• Four upgrades that change how you move
  • Mover: sprint
  • Grappler: wall jumps
  • Battery: higher jumps
  • Rocket
• 50+ pieces of scrap to find across three areas
• Place your own spawn point mid-level, with zones where you can't
• New Game+ carries your upgrades into the next run
• Speedrun timer tracks your fastest and total time, plus a death counter
• Controller support: keyboard, Xbox, PlayStation, and generic gamepads (an analog stick plays best)

A Red Rook Interactive game.

🛠️ Tech

• Engine: Unity 2020.3.28f1 (LTS), C#
• Physics: 2D Rigidbody2D, with raycast-based ground and wall detection
• Animation: Unity Animator state machines for the player and enemies
• Builds: WebGL, Windows, macOS

🧱 How It's Built

All gameplay code lives in Assets/, hand-written in C#.

Area	Scripts	What they do
Player	PlayerController PlayerGrounded PlayerHealth PlayerAnimation	Movement, jump charge economy, spawn-point placement, death and respawn, three-ray ground check, wall detection
Upgrades	ComponentMover ComponentGrappler ComponentBattery ComponentRocket ItemManager	Pickups that unlock abilities and manage the charge meter
Items	BasicItemSmallCharge BasicItemLargeCharge BasicItemOverCharge Scrap	Charge refills, the temporary overcharge state, collectibles
World	Piston PistonSide DoorButton MainDoor Portal SpawnPoint	Hazards, doors, and level flow
Enemies	ArmorBot DozerController	Enemy behavior
Game State	GameManager GameData	Upgrades, scrap, deaths, and times held in a static class for the session, so they carry across scenes and into New Game+ (nothing is saved to disk)
UI	TimerController ScrapCounter HoverText Pause + more	HUD, speedrun timer, tutorial prompts, pause screen
Audio	AudioManager Music Sound	Music and sound effect playback

⚠️ Known Limitations

An early project, and the code shows it:

• PlayerController handles input, movement, death, respawn, and debug tools in one class. It would be split up today.
• Many fields are public where [SerializeField] private is the better choice.
• Systems find each other with FindObjectOfType at startup, and health is polled every frame instead of raised as an event.
• Animation states and tags are string literals, so a typo fails silently.

▶️ Running the Project

1. Install Unity 2020.3.28f1 through Unity Hub.
2. Clone this repo and open the folder in Unity Hub.
3. Open 01-Start from Assets/`Scenes and press Play.

Note

The scenes folder name starts with a backtick so it sorts first. Scene order is set in File → Build Settings. A controller is recommended.

📜 Version History

Development ran from early 2022 into 2023, and the project has been on hold since, with more planned. It used Unity Version Control (Plastic SCM). This repository was created afterward, so its commit history doesn't reflect that work. Devlogs covering development are on the itch.io page.
