Not sure if you knew already, but I already discussed that idea in the original post, and how a partial door is different from that. Check the 4th sentence.
For the first question: I assume you're referring to a combo door. In that case, It would just be impossible for a combo door to have two partial locks of the same color. For the second, no.
The way partial doors would work is that if you don't have enough keys for a partial door, you would still be able to open the door partially. As an example, if you had two blue keys and a partial blue door that requires 4 keys and you try to open it, all your blue keys get removed, and the key requirement of that door gets decreased by the number of keys you had. So in this case the key requirement would change from 4 to 4 - 2 = 2. Now, this may seem equivalent to just having multiple one key doors in a row, but there are a few key (heh) differences. First of all, you would be able to open a partial door with just one master key. Second of all, you can make partial doors have high key requirements which otherwise would require A LOT of one key doors. Third, if you don't have enough, it acts like a blast door with it using all your keys.

Cool game, was able to finally get the highest possible score of 24! By the way, what does the title actually mean? Edit: Tried to get the lowest possible score, and I'm pretty sure it's 4.
Ok, wasn't expecting anyone to speedrun my game, but here I am I guess. As for the curves, I made a circle, then cut out a hole in the middle, creating a donut. I then cut the image in quarters.
