I wanted to create fire shooting eyeball combos by putting a statue on layer 0 and an eyeball combo on a layer, but it didn't work because the Eyeball A doesn't work right on layers. It never points at Link, and it will not point South no matter what you do. Here's two images.
Here it is on Layer 1, malfunctioning.
Layer 0, functioning correctly. Just showing you this as a comparison.
I'm using 163, I haven't tried it in a later beta, as I haven't hear anything about it. It'd be nice if this was fixed, because if somebody wants to place a sprite on a layer and have it always face you (as some sprites do in other Zelda games), it won't work right.
