Thanks for playing! Not intentional, there was a weird bug I ran into with the slime AI where it seems sometimes they were able to lock onto the player just fine and follow them around but at other times it seems like the target acquisition just wasn't working. Their idle AI was awkward too, since it picks a random direction to move in every frame rather than picking a target location to walk to, then picking another random location after reaching it. I'll try to double check the behaviour in an update.
