Before, we opened up the compiled game file (BUILDwin) and looked at what was packed inside. We found a cute 2D platformer where the player jumps around in a little pixel-art world. But recently, the actual source code files arrived on my desk under a new folder called BUILDwinSourceCode/.

This time, instead of guessing what the game was doing from the outside, we can actually read the scripts that make it move. It gives us a much clearer picture of how this project is put together—and spots where it might just need a little tuning before it's ready for anyone else to play.

The Character Is Actually a Penguin

If you look through the animation files, you'll find they are all named after a penguin. It uses a sprite pack called "Nine Pines Animation," which gives the character idle, walking, jumping, and wall-sliding frames. The game separates the visual sprite from the physical hitbox, which is a smart way to keep collisions accurate while the art looks good.

You'll also notice there is an empty script called AnimCtrl.cs. It's completely commented out. It looks like someone started planning a complex animation state machine, realized it was too much for this project, and put it on hold. Not a bad idea—sometimes you just don't need that much complexity.

How the Game Actually Moves

The main character script (playerMovement.cs) runs about 340 lines of code. It uses Unity's built-in physics system (Rigidbody2D) to handle movement, which makes things feel smooth and natural. The developer included some very thoughtful touches:

There are also simple scripts for moving platforms, spike traps, and level transitions. Everything is straightforward and easy to read.

A Few Things That Could Use a Tune-Up

Reading through the code revealed a handful of small issues. These aren't dealbreakers—just things that usually pop up during development. Below are some gentle suggestions on how to patch them, along with the actual C# snippets you'd need.

1. The "Silent" Timer

The timer script relies on finding a text object by its name ("TimerText") every time a new level loads. If a future level forgets to add that exact text box, the timer will stop working and give no error. It's safer to let Unity handle the connection directly.

// In PersistentTimer.cs, replace the find logic with this:

private void OnSceneLoaded(Scene scene, LoadSceneMode mode)
{
    if (scene.name == "level6") {
        // ... existing final time code ...
    }

    // Instead of GameObject.Find(), use TryGetComponent to safely grab it:
    var timerUI = FindObjectOfType(); 
    if (timerUI != null) {
        timerText = timerUI;
    } else {
        Debug.LogWarning("Timer text object is missing in this scene!");
    }
}

2. The Debug Rays Drawing Forever

There is a red line being drawn every frame to show where the player checks for walls. It's very helpful while building levels, but if someone accidentally leaves it in the final build, it slows down the game and looks messy. You can hide it completely outside of Unity's editor using this simple guard:

// Wrap the DrawRay call in a macro like this:

#if UNITY_EDITOR
    Debug.DrawRay(origin, Vector2.right * facingDirection * wallCheckDistance, Color.red);
#endif

3. The Leftover "Reset" Button

Hitting R instantly reloads the current level. It's useful for testing, but players might hit it by accident and think their game is broken. A safer approach is to only trigger it if you hold the key down for a moment, or attach it to a physical "Restart" button on the screen instead of keeping it as a background script.

4. The Hidden Debug Key

In the level-end script, there is a lowercase method named update(). Because Unity expects methods to start with an uppercase U, this one never runs. Inside it sits a cheat code that presses U to skip to the next level. While harmless, it's easy for someone to accidentally leave this in the final version. If you want to keep it for testing, just wrap the whole block in comments until you're ready to ship.

5. The Unfinished Death Counter

The spike trap script counts how many times the player dies using a variable called deathcount. Right now, because that number lives on the trap itself, it resets to zero every time you restart a level. If you ever want to track total deaths across the whole game, change it to a static int so it stays remembered between scenes:

// In SpikeTrap.cs
public static int deathcount = 0; // Changed from regular 'int' to 'static int'

void RestartLevel() {
    SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    deathcount++; // Now this number actually sticks around!
}

The Verdict

This project feels very close to the finish line. The movement is tight, the level design uses a cohesive forest tileset, and the code structure is clean enough that adding new levels won't be a headache. It just needs those small polish passes—cleaning up debug lines, tying down loose ends, and making sure nothing breaks if a UI element gets renamed.

Development always leaves little ghosts in the wires. The important thing is that the core game works, and now we know exactly where to look when it's time to give it that final coat of paint.
