Your links back up the statement.
The first says the compiler is proprietary and unavailable outside of some beta testers, but may be open in the great and nebulous future.
Or Pi, or iOS, or practically all Android hardware… Kind of a non-starter IMO. Maybe this was marginally acceptable when the language started in '14 but it becomes less so every year.
Blow is designing and implementing a language for making video games, and in particular, for making Thekla’s video games (Jon’s game company). Blow does not make mobile games, nor does he make small, retro-style games that would typically be run on a Pi. His concerns are modern Windows gaming PC’s and the big three consoles. While Jai is Turing-complete and is ‘general-purpose’, the implementation serves Blow’s needs first and fioremost, so the chosen targets make sense in light of that.
Given that he and his team are developing a language and a game in that language at the same time it makes sense to focus on the primary platforms they work on, and expect their game to currently run.
Their primary platform is Windows, and the game in its current very early state is also running on Windows.
What's the value in porting it to Raspberry Pi or Android?
From the streams it looks like a Linux port is usually mostly up to date, and MacOS understandably lags behind. But neither of these platforms have any high priority for now.
Yeah, I guess that’s true as far as Blow goes. But there are other people interested in this thing (hence why the OP exists and why we’re commenting on it). And I presume not all of them want to lock themselves in to the apparent dead end that is the x86 platform in the current year when both cross-platform languages and cross-platform game engines are all over the place.
