@0t0_Yoshikawa I've been playing BoF4 for over 20 years. I love your work!

This started as a flat 2D floor plan.

and I'm sharing the exact AI method I used to turn it into a 3D tour inside freepik Spaces 🧵

@pretzelhds that was a crazy ride! https://t.co/3jnYN1UYSD

Stop making boring ads! 🛑 Playable ads turn passive viewers into active players. 📷 Boost engagement and ROAS by letting users "try before they buy." High intent, low friction. 📷🚀

The 3.6kb Tic-Tac-Toe playable ad is live! ⚡️

Unity Luna build: 4,000kb. 🦥

No loading bars, no friction—just instant gameplay and pure ROAS.

@tama20013 Lovely design

[The Pair Programmer @cesarkohl]

I'm rebuilding Tic-Tac-Toe as a playable ad.

📦 Game size: +45MB
⏳ Unity Luna: +4MB
🚀 My goal: <5kb

No loading bars. No wasted impressions. Just instant ROAS.

@helderbuilds I’m aiming for sub-5KB total. One hit, instant play! ⚡

[The Pair Programmer @cesarkohl]

Can we build the world’s leanest playable ad? 🏗️

I’m building a Tic-Tac-Toe playable with the smallest payload possible. In UA, speed is everything.

Every byte saved = better ROAS. 🤏

@appi404 100%. Friction is the ultimate ROAS killer. Aiming for that 'blink-and-it's-loaded' experience! ⚡️

[The Pair Programmer @cesarkohl]

I’m spending 2026 proving that Unity is killing your ROAS. Most playable ads are 5MB of engine bloat and 1MB of fun. I’m learning to build native-first. Follow along. #playableAds

@jie_xiao3721 Dear Soyoo team, I came across your page and was really impressed by your portfolio, which I consider top notch! I am very interested in entering the playable ads market, and it would be a great pleasure if I could learn a bit from you.

@mrx1983 I fixed the issue without downgrading the browser. Take a look at "If error" section.
