Custom enemies using the "4-frame, ...etc." animation style seem to animate incredibly slowly; slower than pre-set enemies using the same animation style. For example, compare a Moblin to a custom enemy with the "4-frame, 4-direction" animation selected, with the same movement rate... it animates more slowly.
4-frame custom enemy issue (b16)
well, it possible doesnt change the animation speed. resulting in both animating at the same speed but the 4 frame enemy is a couple frames longer thus it looks slower.
This is not a bug. I found how to edit the frame-rate under the "data 2" tab.
