so I've been poking around at Platine Dispositif's unnamed doujin shmup from Comiket 87, also known as "____". The reason it doesn't have a title is because the entire thing is written in a conlang with completely unique letters and numbers that don't exist in any character set.
Poking at it has included trying to 1CC it (there's a lategame boss that I absolutely do not understand but if I can figure it out I can probably pull it off), but also trying to see if I can make anything of the language. The letters are probably out of reach, especially since the developer is Japanese so I have no idea if they line up with English or Japanese or any other language, but the numbers are something I've been wanting to figure out, and today I made a breakthrough: it turns out the game's caravan mode has a counter that keeps track of the number of items you've collected, and it counts up directly by ones! with this, I was able to catalog every unique digit. here is the result:
As you can see, the number system is base 12. One other thing to note about the system is that the numbers are written backwards; in numbers 12 and higher, the lowest digit is on the left, with the higher ones moving towards the right. Clever trick!
(EDIT: fixed an error; had the wrong digit for 8 up there)
