great and disappointing at the same time
Good to excellent graphics, nice music that isn't invasive, repetitive or too loud, but instead builds atmosphere and a very intuitive and handy navigation system make this on one hand an extremely well-designed game. On the other, the fights with Jason (which are corny and irritating), the very short time it takes to complete the game and very rigid one-door-key-at-a-time system (especially since almost all doors are locked, making the game extremely linear in nature) and the fact a minigame (though atmospherically well thought-out) is both required to do and takes up actually most of the game time, make this game very disappointing from the point where you first encounter Jason.
This game has some excellent points and it would be a shame not to make another puzzle game that expands on its strengths, but there are a number of lessons here that are mandatory to learn before you do so. Still, I commend the work :) .
