Thanks for the questions!

- For ghost behaviors, some of them are picked up from Pacman 80, and for the others, we try to make them stand out by using features they had in previous games or fan-games.

- For frighten mode, I personally don't see the point of having a dedicated look for each ghost, especially since they never got that kind of feature in official games to my knowledge.

- For game mechanics, the ones in Arrangement AC are done, so, expect the boosters, jump pads and the multi-level layouts to work as intended! Kinky's mechanics are currently reworked (it's one of the reasons the demo release is delayed), and for Championship levels, so far, they are using their own dedicated mechanics based on CE2 where you clear the pac-dots to get to the next layout (as I can't adapt the standard CE mechanics to every level).

Speaking of mechanics, this is the biggest thing to work on, as the Pac-Man maze games have various elements to spice up the levels during the 90s-2000 era, but we'll make sure that everything works in a good and satisfying way when the game releases.
