Solo Dev "Checkpoints": Faster Prototyping via Constraints

Prototyping Faster by Building Less

The biggest enemy of a solo developer isn’t lack of skill; it’s unbounded scope. The ability to do everything is a curse when you’re trying to get a game off the ground. You need to learn to build less, and faster. Constraints are your friends.

The Paradox of Choice: Why Limitations are Your Superpower

Ever stared at a blank canvas, paralyzed by the infinite possibilities? That’s the solo dev experience in a nutshell. We can code, design, draw, compose… the possibilities are endless. But endless possibilities mean endless rabbit holes.

The solution? Deliberately constrain yourself.

Instead of thinking, “I can make anything,” think, “I will only make this.”

Types of Constraints: Choose Your Battles

Constraints aren’t about crippling your creativity; they’re about focusing it. Think of them as guardrails guiding you towards a workable prototype. Here are a few examples:

• Art Style: Pixel art only. No exceptions. This immediately simplifies asset creation. No need to learn complex 3D modeling or spend weeks perfecting textures. Use existing asset packs to further reduce time. I once wasted a month learning Blender, only to realize a simple tileset would have sufficed.
• Gameplay Mechanics: Stick to a single core mechanic. Instead of trying to blend RPG elements, platforming challenges, and puzzle solving, focus on one. I spent six months building a complex combat system for a game that was ultimately about exploration. Huge waste.
• Platform: Web browser only. This bypasses the headaches of cross-platform builds and distribution. HTML5 and JavaScript are your friends. Simpler toolchains equal faster iteration.
• Tooling: Use only tools you already know intimately. This is not the time to learn a new game engine. Familiarity breeds speed. I avoid new tools when rapid prototyping, preferring things I can spin up and use instantly.
• Feature Set: Implement only the bare minimum viable features. Think “vertical slice,” not “full game.” Focus on core game loop first. I’ve seen devs build out elaborate menu systems before even having functional gameplay. Don’t be that dev.

Implementing Constraints: The Rules of the Game

Simply deciding on constraints isn’t enough. You need to actively enforce them. Here’s how:

• Document Your Constraints: Write them down. Make them visible. Pin them to your monitor. This serves as a constant reminder of your limitations.
• Regularly Review Your Constraints: Are they still serving their purpose? Are they too restrictive? Are they not restrictive enough? Constraints are not set in stone.
• Use a "Parking Lot": Have a place (a Trello board, a notebook, a text file) to capture ideas that fall outside your constraints. This prevents you from forgetting them but keeps them out of your immediate focus. I constantly have to remind myself, “That’s a great idea, but it goes in the Parking Lot for now.”
• Be Ruthless: Say “no” to anything that doesn’t directly contribute to the core prototype. This is the hardest part, but it’s essential.

Potential Pitfalls: When Constraints Become Chains

Constraints are powerful, but they can also backfire. Here are some common mistakes:

• Overly Restrictive Constraints: If your constraints stifle all creativity and make the game boring, loosen them. The goal is speed and focus, not creative death.
• Ignoring Your Constraints: What’s the point of having constraints if you don’t follow them? This is self-sabotage. Be honest with yourself.
• Fear of Changing Constraints: As your prototype evolves, your constraints may need to evolve too. Don’t be afraid to adjust them based on what you learn.

Example: From Endless RPG to Focused Roguelike

I was once working on an ambitious open-world RPG, complete with crafting systems, dialogue trees, and a sprawling story. I spent months building features that nobody ever saw because the core gameplay wasn’t fun.

I scrapped the project and started over, imposing the following constraints:

• Art: Simple pixel art.
• Gameplay: Turn-based roguelike combat.
• Scope: A single dungeon level.
• Engine: Godot, because I already knew it well.

By limiting myself, I was able to build a playable prototype in two weeks. It wasn’t pretty, but it was fun. And that’s what mattered. From there, I could iterate and expand, always keeping the core constraints in mind. The final product was a much tighter, more focused game than my initial sprawling vision.

A Framework for Evaluating and Adjusting Constraints

Here’s a simple framework for managing your constraints:

1. Define Initial Constraints: Before you start prototyping, list your intended limitations.
2. Prototype and Iterate: Build your core game loop, adhering to your constraints.
3. Evaluate: After each iteration, ask yourself: Are these constraints still helping me? Are they too restrictive? Are they allowing me to focus on the core fun?
4. Adjust: Modify your constraints based on your evaluation. Add new constraints, remove old ones, or adjust existing ones.
5. Repeat: Continue this cycle of prototyping, evaluating, and adjusting.

By strategically using constraints, you can transform the biggest obstacle facing a solo dev – endless possibilities – into your greatest strength. You will build faster, iterate quicker, and ultimately create better games. You will be more efficient. Build less, build better.
