I agree with Orangudan. Cool concept and I like the eye creature design and mechanics, but there's a very high difficulty at the start. I would like to see easier levels at the start for the player to get used to the mechanics before we get to the high difficulty levels.

Ah I see. The beams are a good addition. If that's the case (with the axis) I would make them beam lines instead of a cone. The cone graphical indication suggests they have the line of sight of a cone as well. It would also be better for player experience if there was a small line emanating from it as well (like a laser that fades out) so we can pre-empt when we'll take damage. May I also suggest quicker health regen times - it can feel a little sluggish waiting to move again.
