Solo Dev Speedruns: Prototype Design via Forced Choice

The Solo Dev’s Prototype Accelerator: Forced Choice Design

Solo game development is a brutal gauntlet. Time is the ultimate currency, and every decision needs to be optimized for maximum impact. Forget agonizing over perfect features; you need a playable game, fast. Forced Choice prototyping is the answer.

This isn’t about cutting corners. It’s about ruthlessly prioritizing and rapidly testing core ideas. It’s about making hard choices early, even when it hurts, to save months of wasted development on a dead end.

Defining Your Game’s Pillars

Before diving into mechanics, you need a rock-solid foundation. What absolutely defines your game? What experience are you trying to create? These are your pillars.

Don’t mistake pillars for genres. “RPG” is a category, not a pillar. A pillar is “Meaningful Choice & Consequence” or “Brutal, Skill-Based Combat.” Limit yourself to 3-4 core pillars. This forces focus.

Example: My action roguelike had the pillars: “Fluid Movement & Combat,” “Procedural Level Variety,” and “Player Expression Through Builds.” Everything had to serve those pillars. If it didn’t, it got cut.

Generating Variant Mechanics and Features

Now, brainstorm. Generate multiple ideas for each pillar. Don’t filter yet. Aim for quantity over quality initially. Think widely.

For “Fluid Movement & Combat,” I considered: grappling hooks, wall running, dodge rolls with invincibility frames, and even a “momentum-based” movement system like Titanfall. These are all variations on a core theme.

Common mistake: Getting attached to the first idea. Resist this. Your first thought is rarely your best. Keep pushing for alternatives.

The Forced Choice: Creating Distinct Prototypes

This is where it gets uncomfortable. You have multiple variations, now you need to force yourself to choose between them. Create distinct prototype builds, each emphasizing one specific variation for each pillar.

Don’t try to combine everything. That’s the road to feature bloat and analysis paralysis. If you had two movement systems, create one prototype that ONLY uses the grapple hook and another that ONLY uses wall running.

Case Study: I had two drastically different leveling systems in mind: one with traditional stat upgrades and one with skill-altering augmentations. Instead of trying to mash them together, I built two separate prototypes. The augmentation system felt far more impactful and aligned with the “Player Expression” pillar.

Testing, Analyzing, and Iterating

Now the fun part (or the terrifying part). Get your prototypes in front of players. Observe them. Don’t explain. Let them figure it out.

Focus on how they play, not what they say. Players are notoriously bad at articulating what they truly want. They will show you.

Collect data. Track playtimes, common deaths, and player feedback (use simple surveys). Look for patterns. Which prototype kept players engaged longer? Which felt more intuitive?

Don’t be afraid to kill a prototype completely. If it’s not working, it’s not working. Learn from it and move on.

Killing Your Darlings: The Emotional Hurdle

This is the hardest part. You’ve poured time and effort into these prototypes. You’re emotionally invested. But clinging to a bad idea is worse than admitting defeat.

Recognize the sunk cost fallacy. Your past investment doesn’t justify future investment in a failing project. Cut your losses.

Remember, you’re not failing. You’re learning. Every prototype, even the ones you kill, provide valuable data that informs your next iteration.

Actionable Tip: Schedule a “prototype autopsy” after each test. Force yourself to objectively list the pros and cons. It helps to detach emotionally.

The Solo Dev Action Plan

Here’s a concrete plan to implement Forced Choice prototyping:

1. Define your game’s 3-4 core pillars. Write them down. Keep them visible.
2. Generate 3-5 variations for each pillar. Brainstorm without filtering.
3. Create 2-3 distinct prototypes, each focusing on one variation per pillar.
4. Test each prototype with at least 5 players. Observe, don’t explain.
5. Collect data and player feedback. Track key metrics.
6. Conduct a “prototype autopsy.” Objectively evaluate each prototype’s strengths and weaknesses.
7. Kill your darlings. Ruthlessly eliminate underperforming prototypes.
8. Iterate based on your findings. Refine the remaining prototype or start a new one with new variations.
9. Repeat steps 3-8 until you have a clear winning direction.

Avoiding Common Pitfalls

Here are a few common mistakes and how to avoid them:

• Analysis Paralysis: Don’t overthink the variations. The point is to test them, not perfectly design them.
• Feature Creep: Resist the urge to combine elements from different prototypes too early. Focus on isolating variables.
• Ignoring Player Feedback: You’re not building the game for yourself. Listen to what players are showing you.
• Getting Attached to Your First Idea: Be willing to kill your darlings, even if they’re your “baby.”
• Not Testing Enough: 5 players is a minimum. The more data you have, the better.

Embrace the Speedrun Mindset

Forced Choice prototyping is about speed and efficiency. It’s about rapidly iterating on ideas and making informed decisions with limited resources. As a solo developer, this is your superpower. Embrace the speedrun mindset. Kill your darlings. And get your game made.
