[Journal] Pipeline map_4, new collision detection (Pixiv Fanbox)

Complete view of new map design.

Tried to bring cocepts of : pipline theme oriented, introducing moving platform, new monsters.

As its entrance is tunnel, I wanted to cover hole map entering for the first time.

I think the animation of monster drinking the puddle would be charming. Work in progess.

+) As this map has dome shaped ceiling, I needed to code new collision detection type. Still needs to be actually implemented.
