At first sight, a promising game. Great graphics (I'm wowed for the title), but... ultimately I can't be as complimentary as other players.
Besides the fact that there is no autosave (you don't expect to have to save manually only after 5 minutes of play, especially in the context of the first part of the game), the big lack in my opinion is the accompaniment of the player in the hero's quest, at least in the beginning. There are no "signs" to help the player find his way, nor are there any suggestions on what he should do. You find yourself wandering around the map trying to figure out what to do. Moreover, I find the "Game over" a bit too direct/easy (jumping in the void, answering wrong to acquire a certain crystal). It can be fun (the first time), but frustrating in the long run.
Note: evaluation made on 20 minutes of play that I allow myself, including 15 minutes looking for the last 2 crystals before finishing with a Game Over on a wrong answer.
