Some of the very mobile minibosses are hard to keep a track of, and I have often gotten hit becuase they appear out of nowhere. I don't want to suggest a direct change to the minibosses or their attacks, but what I think would be a neat idea would be to have a useable/upgrade that tracks all the ememies in the room. Basically, use the icons for finding doors or pickups and apply them to ememies when they are off screen. I think this could be valuable, as it could be used for other things as well. I've only played for about 2 hours so far, and I believe it would be helpful for finding the scarce amount of ememies in a trap room to quickly turn off lasers/turrets, and for mopping up after boss battles or large rooms.
Thank you for reading this,
