The secret is...in the title actually! "Ad Infinitum" is Latin for "To Infinity", which may (hopefully) give you a clue as to what the real end result is. Beyond that I don't think I should say any more, I typically prefer to leave story and plot open for interpretation.
Also, I don't know why but I didn't even think of controller support! I'll see if I can figure out how to do that quickly/efficiently for future games, because I'm sure there are many others like yourself that would be much more comfortable on a controller. Even just the keyboard controls themselves were a bit poorly mapped in hindsight though, I'm seeing now that it would be all-around more comfortable if the attack key was on the right side of the keyboard, or on a mouseclick even.
Thank you for playing and streaming it, Endmark! I appreciate all of the support.
