As an answer to ladridi:
I see there's a slight lack of logic in using a rock tile as a deadly tile and using a lava tile covered with rocks as a safe tile. What I'd like to point out is that fundamentally those tiles are just metaphors for safe and unsafe and should not be taken too literally. It's how it works in every game. For a clumsy example: in chess, why can the queen move more than a horse?
There's a point in every games' development where you should meet a deadline and as a compromise something will be left unfinished and unpolished.
I hope everyone can enjoy the game despite the slight lack of logic in couple of tiles.
