"I've used Unity for 10 years. Summer's AI workflow is the first time I felt like I was truly 'designing' instead of just wiring inputs."
"The Asset Store integration is insane. I generated a texture, applied it, and had it running in-game in under 30 seconds."
"Finally, an engine that doesn't punish you for not knowing every single math function. It just understands what I want."
