After going through again and this time taking into account the intended yet unclear silliness in the numbers and the attempts at correcting these by many parties, this should be closer to correct.
Easier than It Looks [-2] (mistakenly given +2 by JB)
Spumoni [0]
(my earlier calculation was correct)
Steam Cleaner Simulator [24] (discrepancies were already corrected)
Culprit [13]
Thief Street [2] (-2)
Chip Alone [-2]
(mistakenly given +2 by JB)
Assassin [10] (over-correcting stuff resulting in extra loss of 1)
Automatic (Caution) Doors [2] (+1)
Edit: Cue music from Frozen for Tom...
(no need to get angry if I heal a non-zero level, even if it has seemed dead for a while, right? I was just trying to set this up so that someone could kill it and Thief Street and heal the negative numbers back to zero. In my opinion, simply forgetting about levels with negative scores results in artificial points for the remaining levels and it would be ideal to heal them back up to zero.)
