# client. The first line calculates the maximum score achievable for a single pixel with the current items in the
|
||
|
|
# worst possible case. This per-pixel score is then multiplied by the number of pixels currently available (the
|
||
|
|
# starting canvas is 400x300) over the total number of pixels with everything unlocked (800x600) to get the
|
||
|
|
# total score achievable assuming the worst possible target image. Finally, this is multiplied by the logic percent
|
||
|
|
# option which restricts the logic so as to not require pixel perfection.
