@Da_GPer I had watched exactly that video, but throughout its entirety the player never gets slimed even once.
@rainponcho: that could only be done with some rom expansion, there isn't a lot of space left. I'm not sure how I feel about expanding roms.
Here is the finished staircase scene!
The building has 10 floors now instead of 23, but I may change that to adjust difficulty later on.
To do: final scene, the other three building variations for the ghost catching level, staypuft man destroying buildings, and the pause inventory.
To make it clear, I don't want to change the mapper or expand the rom, I want the game to use its 1985 technology and see what I can do with it.
