The game is written in C++ and remains my largest project to date at around 25000 LOC.
It starts off as a normal calculator, but gradually transforms into much more. The storyline touches on themes of alternate universes, time travel, the singularity, etc. In terms of gameplay, I would take common elements of software design, such as trouble-shooters, installers, dialog boxes, etc. and distort them in as perverse a way as possible. It at times involved making creative use of the GUI toolkit (Qt) to do unconventional things.
The game includes a Doom-style 3D engine, which I found extremely challenging to develop. I never looked up how to do it as I wanted the satisfaction of deriving my own rendering and collision algorithms. Consequently, it's horrendously slow, which is why the resolution is so low. It has most of the features of the original Doom engine, plus a few more, like portals and the ability to look up and down. I used Inkscape as my level editor, because from Inkscape you can export SVG images, which are just XML, which is easy to parse - I just had to figure out how to represent all the level geometry and game objects in an SVG image.
It got a bit of attention when it first came out, but not much as I never really bothered to promote it. I've decided on a whim to post it here today :)
