Play the game, feel the chaos, and most of all: listen.
The original soundtrack is coming soon to stream and buy, but for now… go make some noise:

Rift Riff's audio guy @matthijskoster.com just HALVED Rift Riff's binary size!
we were already using Vorbis compression (file ext: .ogg) but found that setting the export quality to the lowest number possible barely made a difference in audio quality, yet reducing file size by 75-90%! #gamedev

I think in general, I am a positive guy…However, there are a few things I REALLY hate, like: out-of-tune baby instruments.
This cute little turtle, for example, has a totally off-key upper section, but the hardest part: the lowest note sounds the highest.
Although, I do like the eye being a bell!

Worked on some heavy sound design for this one! Love how layered it is: in your face / subtle atmospheric. 💥🍃☄️🏜️

The new Speech-to-Text feature from Pro Tools will be a game-changer for me!
“Did we record this?” won’t be a long, painful, time-consuming question anymore.
And that’s not the only thing that’s good about this update.👌

This exhibition is a full sensory experience — including sound. My 3,5-minute soundscape takes you through the process of preparing a complete dish: from chopping and kitchen machines to handling fresh ingredients, plating, and pouring drinks. 🍽️🧄🧅🧀🥗🥂

As an Apple Notes power user, the one thing that always bugged me was the lack of a keyboard shortcut for Strikethrough. After running into it for the thousandth time, I finally looked it up — turns out it’s ridiculously simple (see screenshot). Anyone else been there?

Our son Otto is almost 6 months old! I thought it would be fun to celebrate it by naming a song after him. I made this piece of music in 3 hours, in a creative burst. It’s playful, cheerful and headstrong. Just like Otto himself ❤️

Just calculated all folders together. I guess I could work a little more economically, but it doesn't feel like all that much for a year of work.

Learned something about Music today: Apparently, you can’t use the abbreviation ‘OST’ in your album title. I guess this is a stylistic choice they made? Went for Original Game Soundtrack instead. What do you think?

Rift Riff is OUT NOW! I took a leap and let go of most of my freelance work to focus on this game. I never expected it to take a year and a half—but here we are! :D It’s been creatively exhilarating working with the team, and I’m so proud of the little game we’ve built. #godot #pixelart #indiedev

Almost a year in and building this game has been AWESOME! Building a game with this team* has taught me a lot: gamers are dedicated, people building games even more. And the best part: unlike other projects I work on, with games, you DO get (unfiltered) feedback from the audience. Go play, have fun!
