Very hard game. Since you're moving around a lot I would recommend the camera focusing on either the cursor or halfway between the player an cursor, since I felt like I was frantically moving my mouse about as I moved the player. Couldn't see the topic being used here, I guess you could say the size of water but that's just another way of saying your healthbar and it wasn't applied in a unique way. Unless there's something later in the game that I missed, because I kept dying. The enemies fired too often and the rooms where multiple enemies immediately start attacking you was too difficult to avoid.
