RobberDock Games – Robber Wheels (GBJam 2018)

GBJam is an annual game jam where over a week people create games inspired by, or similar to, the games on the Game Boy consoles. In 2018 Iiro Lindell of RobberDock Games and I took part in it, with me creating the music and sound effects and he – well, everything else, really.

What I found particularly interesting about the challenge was creating music that fits thematically. For this I chose to use the FamiTracker software – a chiptune tracker that emulates the NES soundchip and allows users to compose music (and SFX) for it. Learning to use it wasn’t exactly trivial, but once I got the hang of it, there was a surprising amount of expressivity to be found.

Overall the project was fun, and I learned quite a bit about chiptune, and many of the lessons are also applicable in different styles of music. Our submission wasn’t exactly perfectly authentic to Game Boy consoles in particular – NES has one audio channel more (for five total) and I used the NCO expansion chip in Famitracker, bringing my total channel count to 7 – though I chose not to use the DPCM sample channel as it didn’t sound very gameboyish to me.

RobberDock Games – Sheepwith OST

Sheepwith by Iiro Lindell / RobberDock Games is an arcade-style flying game where you rescue sheep from wolves and other hazards. I had the pleasure of writing music and doing some plane sound design for the project.

It was the first of my larger projects, and one of Iiro’s as well – and as such a fair amount of time was spent learning to communicate with each other – with people of different skillsets and interests. In the end we opted for the bright, upbeat, kind-of-funky style of music that you can hear above. In retrospect the mixing is perhaps a bit too bright, but overall we were (and at least I still am) happy with the general results: the songs are quite catchy, they all fit the theme of the levels, and definitely the overall aesthetic of the game.
