Hi john4p,
This morning I managed to play through the game without deaths and my score was 100.0. Using the formula to calculate the score I would think to have gotten 111.3:
Total score = 30 + (7.0+7.5+22.0+2.8+42.0) = 111.3
I didn't divide by 0 deaths here, because that's impossible. Now I ask myself, would I have gotten 111.3 when I would have died once? Or is 100.0 the maximum score? When I calculated my previous scores with the formula the total score was as expected.
I hope I will manage to get to the end again with one life lost, or without losing a life, so I can maybe let myself get killed once by Death Adder to try this out...
