Other mistake: In the temple, there are some small floor platforms that are like a staging area where a podium or statue might go. A base of sort. They are just a couple of pixels on top of the floor and the Slayer will just walk over them. However, when going over them, it sort of triggers the flip animation of the Slayer sprites as if you're jumping through the air, for a couple of frames, then back to just walking. As if stepping on a small board makes you flip.
Other mistake: In the Factory dimension, there are various buildings going by in the parallax scrolling background. One of the buildings has a large staircase and walkway up to a ledge where an entrance into the building should be below a window. However, there is no door on the building where one should be.
