Spring has arrived in GoBattle.io! 🌸 I am really happy with how the new boss turned out, drawn in Aseprite and animated in Spine. If you love old-school platformers, you should try it! ⚔️🎮 #PixelArt #IndieGame #RetroGaming #GoBattle #GameDev #indiedev

I recently had the honor of interviewing Zen’s chief architect Mike Clark! I tried to fit in as many microarchitecture questions as I could, including x64 vs ARM ISA power efficiency, 4k vs larger page sizes, 64-byte cache lines, scatter/gather and more:

I understand Apple wants users to know better what they download, but they should fix macOS permissions instead. Right now, it's a mess. If you miss the permission dialog, it's almost impossible for a normal person to find the setting again without a map. www.macworld.com/article/2628... #MacOS #UX

I’ve added an API to Uxperior that lets you use the desktop capture as a texture, allowing shaders to transform the content. Here’s a privacy filter done in just 50 lines of code (code in the video). I’ll make all filters open-source so anyone can create their own! #MacOS #IndieDev #buildinpublic

I’ve added an API to track the position of windows on macOS, enabling Uxperior plugins to do things like create custom skins or interact with window edges. In this video, you can see a skin for the Apple TV app that transforms it into a vintage TV! 📺😊 #MacOS #IndieDev #UIUX #RetroTech #buildinpublic

Carsick.app has passed $200 MRR! 🎉 The Windows version is almost ready, and I’m hoping it gives things a nice boost. 🚀

The new version of carsick.app with background support is ready on the App Store! I was not sure Apple would allow it as I had to do a hack to keep the Bluetooth connection in the background.

I’m developing a new Mac App that lets you customize your Mac’s UI with customizable effects powered by my 2D engine. It supports shaders, animations, and full programmability with LUA. I’ll also release the source code for all effects. Let me know if you’re interested! #macos #indiedev #ux

Balancing a game is so challenging! We made a change to GoBattle’s King mode that increased the average playtime by 25% and better balances the skill of new players. But now some high-level players are complaining because it relies more on skill. #gamedev #indiedev #GameBalancing
