I like the abstract atmosphere of the environment. The mechanics are simple and easy to learn. The setting is also fitting to not just the theme, but the mental state of pretty much everyone participating in the jam. The weird background voice is also an interesting addition.
I have a bit of a problem trying to see the enemies since they can sometimes blend into the environment. Some sound effects/particles when they spawn might also be a good addition. I think that the movement between the head can be made smoother. I feel like if the player is touching the edge of the head, it should be in range to move to the neighboring head.
Great job on the jam!
