Way too easy.
If I rate this game due to the serious lack of harder puzzels. You would definitely fail. However I belive that the sound was so original and well composed that i decided to keep playing.
Things you need to improve on in your sequel.
1. Harder Puzzels
2. Better Picture Quality (which is crucial in these types of games)
3. More Fast Pace
4. If possible make the story a little more deeper (EX adding a romance or some sorta new thing.)
5. (I can't say this enough in every type of game like these.) Unless you get you make the tab key useless most people will be done your game very quickly and will miss the entire plot of the game. (thus giving you bad reviews)
I look foward too seeing your automaton part 2.
(please listen too my advice i garentee they will imrove your work to perfection!)
Good luck.
