Rose: Does downwards spear attacks. Can tether enemies to surfaces if she has 2 spears on hand (needlekind). Has a color indicator on the screen edges to see enemies on the next screen (seer).
John: Gravity manipulation, can do long flighty jumps (breath) but can also do slam attacks (hammerkind).
Jade: Can change size (space) and do short dash teleports (beq). When she's large, most enemies are too afraid to attack, but she can't go through tubes and tunnels. When small, she is very fast like a bug but it's instadeath if attacked, and creatures that are usually passive attack when she's tiny. Oh also she can spawn a rifle anytime (riflekind)
Dave: Uses spears as a sword (bladekind) and can slow and speed up time at will (time). Rolls infinitely (SBAHJ).
