Sorry I don't know what you mean. In my version there's a couple of pixels leniency either side of the centre of the wally sprite before you fall.... but I don't get what this has to do with the static sprites
Here's the comparison between two games: original Automania is above, Automania Refurbished is below. In both cases, Wally's next step will lead to his death. Note that in the top version, Wally has passed exactly half of the BP canister, while in the bottom version, he's passed at most a third. Clearly, in the original game, Wally dies when he passes half the hazard, while in your version, it's about 1/3. This makes the collision detection feel much stricter.
