Aaah... I played this one tons of times. It was not perfect for me though, there are a few instadeaths here and here and the necessity to eat spoiled quite a lot of the fun. However, I still managed to enjoy it, it is just that I think that an adventure game should penalize you only for something really obvious and let you to take your time to think. I this regard, I don't believe that having to eat in a mandatory way helps :)
On the other hand, I think that the vector grapichs in this game are among the best on its class...
Ah the joys of watching the lines appear and then the shapes getting filled in... :D
Well, it's almost impossible to finish without a guide...Not easy to know by yourself to do...
