I started working on a raylib binding for pharo using pharo's ffi...I have to say pharo's ffi system is very easy to use. It works and I got a few demos working, but I haven't put in the function calls for most of raylib. https://github.com/Zenchess/pharoRaylib
There's also native pharo smalltalk stuff like athens, woden, and maybe others...
Personally I have moved to using Dolphin Smalltalk and raylib bindings there as it's been more performant and I prefer Dolphin over pharo. Dolphin also has good external interfacing support and is more of a native Windows OS smalltalk distro. If you're looking for building native windows looking applications on windows at least probably your best bet is dolphin and it's free and open source.
Just a heads up the pharolauncher does not seem to be working for me, at least for pharo 9. Manual download of vm + image 64bit works but 32 bit does not.
I have been making pharo raylib bindings and plan to make a video soon about why Smalltalk is an interesting choice for game development, it's a very 'live-coding' feel, i.e. you run your game while the editor is still live, you have free reign to at any time modify the methods of all game objects, execute random code, etc. without restarting the game...
I always use smalltalk when the problem would allow for it since I'm much more productive in smalltalk than anything else.
It's great for certain random tasks - i.e. Want to set up a websocket server for some reason? Program it in smalltalk, test it interactively (literally debugging on execution errors, fixing and resuming execution until it works).
If I'm writing a native windows app I'll go with dolphin smalltalk which imo is much nicer to work with and gives you a native gui. I have to say though pharo is getting better all the time and has an active community.
