Is opening up your source code worth it? Terry Cavanagh thinks it was for VVVVVV

A lot of game developer still worry about being more open with their code but it seems Terry Cavanagh (VVVVVV, Super Hexagon, Dicey Dungeons) believes it was worth it.

There are certain legitimate reasons to worry about going all-in with open source, but we're not here to debate that. Plenty of developers have warmed up to the idea of open source over the last few years, with Cavanagh now being amongst them. Cavanagh opened up the source code to their puzzle-platformer VVVVVV back in early 2020.

Now on the 11th anniversary of VVVVVV's launch, Cavanagh has a fresh blog post up to go over a previous Game Jam but they also gave some thoughts on the source code drop too. It's worth pointing out though, the code is open but not under a proper OSI-approved open source license. It's certainly a good step though!

So what happened? Well they accepted and merged over 400 pull requests from the community, which will result in a big new release of the game later this year. They got a port to the Dreamcast, the Haiku operating system and there's also a webassembly port now too.

Summing up their thoughts on opening the code, Cavanagh said "So, I guess for other game developers thinking about doing this, here’s a data point! Only good things have happened. This whole thing has been a really positive experience, and I’m really glad I did it.".

Nice to see such a healthy experience!
