Neat idea! I didn't understand at first why I would want to absorb the enemies, until I noticed that they don't stay down permanently. Did the different coloured bugs have different effects? I felt like there was maybe an elemental type system happening depending on what bug I had attached to my flail but I couldn't quite work it out.
Also, I think binding the camera to the player OR making enemies that can't transition between rooms would be a good addition - it doesn't quite work with both at the same time.
Good work though, had fun with this one!
