HAX
About
HAX is a Zork-like text adventure where the only way to progress is through save-file "hacking". NO PROGRAMMING EXPERIENCE REQUIRED! It was created in the LOVE2D engine in one week for WoGaDeMo 2012. A hint system is available here.
The Windows standalone package is included in the download. Linux and Mac OS X users must download LOVE2D and use the included .love file to play.
