It's a hard game.
Its puzzles are hard, sometimes hints leading to them are very vague and hard to decipher.
The professor's jumps are hard to master, making it hard to judge distances.

But hell, this game is great.
Despite everything, I pushed on and on and on, and I was rewarded greatly.
This game's soundtrack is a complete banger, and the story is incredibly rich, with stone tablets and archaeological facts absolutely everywhere for you to enjoy.
It feels great to see a hint for a specific puzzle, then find where you have to apply it.

I'm going to warn you, though.
This game isn't for everyone, and it will only appeal to people crazy enough to take notes on EVERYTHING the game sends toward you, with the exception of archaeological facts, they're displayed differently on screen.
If you want to take this game on, be ready, it's a hell of a ride, even more so if you want to experience everything this game has to offer, including some stuff not meant for the human eyes.
