You know, here at CNET Australia, we were just thinking that the world would be a better place if we could play Portal on a Texas Instruments graphing calculator. We think Omnimaga contributor Builderboy must have been reading our mail.
Seriously though, this home-made little (very) old-school game looks pretty sweet. Before the days of GLaDOS, you are an Aperture test subject finding your way through 38 challenging Portal chambers.
We'll be right back. We just have to go calculator shopping.
You can download Portal Prelude from Omninaga for free here.
