Trolley Problem was written in ActionScript 3 using Adobe’s FlashBuilder 4.5 and the excellent Flixel library. It uses a sound effect I made in bfxr and the title track was made with WolframTones. The font in Trolley Problem is Commodore 64 Pixelized by Devin Cook.
You can read my writing about the game on my blog. Trolley Problem was written about on Alphr.
Trolley Problem has appeared in the exhibition The Games of Art at the QUT Creative Industries Precinct.
This game was exported in Flash and, as you probably know, Flash has been discontinued. As such, I’ve made a Ruffle-based emulation version, the source code, and the original .swf file available at the moment. For some reason you can’t switch tracks in the tutorial level? Ah, emulation.
