As of 2021/11/24, my Ollar calculator for the first Scribblenauts has been updated (link). The 2 key updates are:
- Hovering over/tapping an input container shows a more detailed explanation of what the input is for
- "World" dropdown was replaced by 3 dropdowns to select a specific level, so that no impossible par values can be entered.
All the data I used to make the calculator is from my original research. I have seen at least one case of the difficulty and par in a level being inaccurate on this wiki (perhaps whoever put in the infobox template used some default values?), but I haven't gone through every level to see if any more are inaccurate.
If someone is bored and wants to check literally every original Scribblenauts level to make sure the par is accurate, I have compiled the par data for every level into this Google Sheet for reference, along with some simple statistical points of interest.
