Space Invaders on Unity

Dev Vlog #1 – Rebuilding a Classic

Hey there!
I wanted to write this devlog to share a bit about how it’s been recreating my own version of Space Invaders using Unity. The idea started as a personal challenge — I wanted to see how close I could get to the feel of the original arcade game, doing everything from scratch.

🎨 Visuals

All the sprites were made by me. I tried to stay true to the original style, but with cleaner, modern pixel art. The player ship, enemies, shields, and UI were all redrawn by hand. Nothing too fancy, but it’s all mine.

🧠 Mechanics

The core gameplay follows the logic of the original as closely as possible:

• Enemies move as a group and get faster as their numbers go down.
• Shields break down piece by piece when hit, using a simple destructible tile system I built.
• Player movement is limited to the sides, but it feels responsive and smooth.
• Bullets follow a basic firing delay system, both for the player and the enemies.

🎮 Controls

• Arrow keys ← → to move
• Spacebar to shoot

🛠️ Still to Come

There are a few things I haven’t implemented yet:

• Audio: No sound effects so far. I’m planning to add retro-style SFX soon to match the gameplay vibe.
• Second Player Mode: I’d like to add support for two players, either taking turns or playing together. Still figuring out what feels best.
• UI improvements: The start and game over screens are super basic for now. I want to polish them later and maybe even include a high score system.

✍️ About Future Devlogs

I’m planning to write more devlogs soon, focusing more on the source code structure, some of the architecture choices I made, and the techniques I used to recreate specific mechanics. Nothing too fancy — just honest documentation of the process, in case anyone finds it useful or interesting.

💻 Open Source

The whole project is open-source. Feel free to explore the code, reuse parts of it, or contribute.

Thanks for reading :)
