New Enemy: Pulse Core
What are these mysterious orbs? They don't look very menacing. They only follow a fixed path and are in no way aggressive. They don’t even deal damage to you if you touch them, instead they throw you away, which to be fair, can be just as deadly.
There is also their cousin, the Pulse Gate, but as it’s static and totally predictable, it’s not much of an enemy, maybe rather a tool?
