Great game
The ending made me feel quite superior >:D
I enjoyed moretheless fighting this machine as well as the riddles.
Also it feels like my frustration with puzzle games is reflected by this, as trail and error is a big part.
---SPOILER ALERT---
First Room: examine bed and get the key
Second Room: Substract it´s age from the Year given and type it´s date of birth.
Third Room: Type random numbers while it insults you, after several tries you it will tell you that what you just typed was right. (The actual numbers don´t matter)
Fourth Room: just type something until it is fed up and gives you the task to guess a number between 1 and 100,000. It will also tell you if you are too high or too low. Easiest way is (high or low are just examples as it will take a RANDOM number) first guess: 50.000 if too high then go to 25.000 to low go to 75.000.
25.000 too low -> 30.000 to high 29.000 too low -> ect.
in the next room it will cut of your hands. Examine the blood and the type random things until it asks you to name one more unneccecary feeling that you have. type "ANGER". This is basically when you defeat it. After that just type leave and you´ll be free
