Concept vs Final Game

Commander Cockerel and the Undead stayed true to the heart of the concept: a chaotic, wave-based arcade shooter with a comedic horror farm twist. The core idea — survive as long as possible while blasting zombies and collecting power-ups — is fully intact. That said, a few features evolved or didn’t make it in (yet), and here’s a breakdown of what changed and why:

What Stayed the Same

Core Gameplay Loop:

• Survive endless waves of increasingly tough enemies
• Earn points by eliminating zombies
• Collect pitchforks for random power-ups and grenades
• Beat your high score and repeat the chaos

Key Features Implemented:

• Egg Grenade: Works as planned — drops behind the player and does big damage
• Dash Move: Lets players zip through tight spaces and avoid getting cornered
• Strategic Obstacles: Fences are used to create visual and functional chokepoints

Map & Level Design:

• Gritty haunted farm with a coop-style starting area
• Grave markers as enemy spawn points

Visual Style:

• Retro pixel art with cartoon horror flair
• Chunky outlines, exaggerated animations, and a consistent pixel aesthetic

Character Design:

• Commander Cockerel: Looks exactly how I imagined — a tough rooster in military gear armed with a machine gun.

Sound FX:

• Features zombie moans, egg bomb explosions, ambient farm sounds, and the signature rooster crow

Progression & Replayability:

• Waves get harder with stronger, faster zombies
• Power-ups offer replay variety and improve survivability

What changed and why

• Brain bomb – the brain bomb wasn’t included because the focus was placed on polishing the mechanics of the existing power-ups. May add later.
• Mud pits – mud pits were actually included but just as map tiles and not to slow enemies down. May implement later.
• Enemies/character design – originally I planned to have farmer zombies and obese farmer zombies as the tanky enemies. I changed this to little pixel art green zombies as I couldn’t find a eight direction sprite sheet for a “farmer zombie”. This design looked cool and still fit the theme.
• Sound and music – the music does not include a looping banjo-fueled track that gets more intense with each round. Was difficult to find a track that was exactly what I was looking for so settled for some audio that fitted the theme.
• “Survive 10 rounds to open all areas” I scaled this down to first gate is opened a round 3, which opens the whole map and another gate opens on round 5 too add the player being able to loop around the map. This was scaled down as 10 rounds was way too long and I needed more action faster.
• More weapons – no more weapons were implemented other then the machine gun. Although the power-ups add abilities like the egg bomb to the arsenal.

Summary

The final game delivers on its core idea — fast-paced, chaotic fun with a rooster blasting zombies. It’s silly, intense, and plays just how I imagined, even without every planned feature.

Testing Feedback & Changes

In Week 12, I ran a playtesting session where classmates tested Commander Cockerel and the Undead. The feedback I got — and the things I noticed while watching people play — really helped me polish the final build. Here’s a breakdown of what was tested, what came up, and what I changed:

Wave Timing & Flow

Feedback: One tester mentioned they weren’t sure when a wave ended or when the next one was starting. They also said the time between waves felt way too long, which dragged things out and stopped them from seeing later features.

What Changed:

• Cut time between waves from 10 seconds to 5
• Added a 3..2..1 UI countdown with matching beep audio
• Added a cinematic boom at the end of each wave
• Made enemies get tougher faster
• Opened the full map at wave 3 instead of wave 5
• Triggered new zombie types when the full map unlocks

Pitchfork Power-Up System

Feedback: Some testers never found the pitchfork power-up and didn’t understand how it worked. It was too random and confusing.

What Changed:

• Reworked the logic completely
• Pitchfork now spawns once every round instead of only between waves
• Added a fixed spawn point in the starting area at the end of wave 1 so players always encounter it
• Created an in-game UI instruction panel that appears the first time a pitchfork is found to explain the system

Audio Balancing & Bugs

Feedback:

• Audio levels were too loud or clashing
• The rooster crow (which now plays when you collect a pitchfork) sounded glitchy
• Machine gun audio didn’t play properly when just clicking (worked better when held)

What Changed:

• Added rooster crow to the AudioManager and tweaked its volume + trigger point
• Balanced overall sound mix with volume sliders in the inspector
• Tightened up the start of the gun audio clip so it triggers even on quick clicks

Enemy Hit Detection

Feedback: Players were taking damage from zombies even when they weren’t touching them — felt unfair.

What Changed:

• Reduced zombie attack range via the inspector
• Tightened up colliders on both zombies and player
• This made hit detection feel much more accurate and fair

Restart/Replay Bug (WebGL)

Feedback: When restarting the game or returning to the main menu and starting again, the player would get stuck — no movement, no bullets, no zombies.

What I Found: This only happened in WebGL builds and took a while to track down. With help from my professor, I found the issue was caused by the “New High Score” scene that was triggered after a game over. It somehow messed with reinitializing key systems when reloading the main game.

What Changed:

• Removed the high score scene and all related scripts
• Instead, added a new high score input panel directly to the game over screen
• It now only shows up if a high score is reached

Note: It’s not the cleanest UI setup visually, but it was more important to get restarting and high scores working reliably. I’ll improve the look later.

Final Thoughts

This round of testing made me realise how easy it is to overthink or overbuild certain features when you're the one making the game. What made sense in my head (like hiding power-ups or delaying map unlocks) ended up confusing new players or slowing down the fun. Having outside perspectives helped me simplify and improve the experience — and made the game a lot more accessible and fun to replay.
