Back in the 90s, it was a game as Java applet. But then somebody removed all those nice plugins. I ported it a while back to C#, made it into desktop (Gtk, WinForms etc), but now finally, it returns - with WebAssembly - back into the browser, where this originally “remastered from DOS” game began 😀
