Testing a game is fun 🙃 You need to cover different platforms, different player levels, different devices... Think I need to figure out how AI can do all of that - any idea where to start the automation?

I don’t think Tiny Harvest needs another feature right now. It needs more people to find it. That’s a much harder problem to solve.

If you want to lose weight, doing more sports is rarely the answer. It's 95% about what you eat. When I actively train, I am so much more hungry all the time that I have a hard time staying in a deficit at all.

Running a Product Page Optimization test for the first time ✌️ My games CR isn't great, and instead of randomly trying things, I made a test in ASC: - Original page - Simply a new preview video - New screenshots Traffic split equally between the 3, let's see if there are any meaningful trends!

I have to set up a new Google dev account and transfer my game 🙈 Wish me luck in the migration. Will share how I did it and whether it worked!

Not the most popular keywords, but trying to grow on some new ones like "acres" and ranking better on "stardew valley" ❗️Note: Don't directly use a competitor keyword or you get in trouble

Current priorities: ✅ August season ✅ Bugs & QoL ✅ TikTok ✅ Reddit ✅ X Trying really hard not to hide behind “just one more feature.”

My game finally hit $5,000/month. For a few weeks, I thought: “Nice, this is my new normal.” Then installs dropped again. Why? 👇

The next few months I’ll probably spend just as much (or more) time on marketing as I do writing code. Weird shift, but it feels like the right one.

June 2026 income report for my mobile game Tiny Harvest 🌽 💰 $5,831 revenue 👥 6,145 new players Still blows my mind that this little farming game is becoming a real business.

I built an AI voice notes app with React Native. And AI agents wrote most of the code. Call me a vibe coder, but this is how you build great apps in the age of AI 👇

My latest video about AI thoughts seems to resonate with many of you. It’s about what AI has changed for me, why I’ve been building indie apps instead of courses lately, and why my YT channel is changing. Maybe we’re all figuring this out together.

"Pay 2 win." Every player hates these games. Every indie dev fears these comments. And yet here I am, telling you that it’s probably the best way to monetize and actually make money with your app. Here’s why I still use in-app purchases in my game 👇
