Not really a puzzle game.
The exciting thing about puzzle/adventure games is trying to see if you can figure out what to do, and feeling good about it when your train of thought proved correct. These challenges in the game need to vary in both difficulty and medium, so as to cater equally to all types of thinkers.
Your game is just a series of identical doors, each leading to instant death or an eternal purgatory of random clicking and false hope. Every puzzle is exactly the same, the only difference between them all are the answers and the clues, the latter of which range from the painfully obvious (3 2 1) to the frustratingly obtuse (what the hell am I supposed to do HERE?).
The ideal experience should put you in the mindset that you're being manipulated by someone much smarter and more organized than yourself, not that you're playing a game thrown together as quickly as possible, using obscure clues and apparently randomly-generated sequences of fatal choices rather than their own cleverness to stump the player. That's false difficulty.
