Using low-fidelity prototypes – such as simple sketches, quick paper mock-ups, or crude cardboard models – is the fastest way to reveal the truth about a concept. This early experimentation helps prove the viability of the core idea by quickly testing key mechanics and player engagement.
Crucially, the prototype’s obvious lack of polish actually elicits honest feedback from testers, as they aren’t distracted by slick visuals or complex features. Even better, that low level of polish means the team hasn’t become emotionally invested, allowing you to pivot faster when the feedback hits.
Ultimately, keeping the prototype simple forces you to distill your game down to its absolute base elements, ensuring you focus only on the things that truly matter.
