Hi there! This pack is designed for platformer games, so there's only 2-direction movement (by flipping the sprites). Sorry to disappoint. I'll have to put 4-direction monsters on my to-do list!
No worries, and I appreciate you adding it to a feature update, I will deferentially keep eye on it until then.
I'm not sure if I'd be able to do it for this pack specifically... The perspective on the monsters is side view. If I did 4-direction monsters it'd likely be a more top-down perspective and an entirely new asset pack.
