Enemies[edit]
Keeper
"Moving around the room, shooting 2 short-ranged blood shots in a "V" formation. Getting hit by its shots wil cause the player to lose some of his/her coins"
Tip: When they're shooting, make a line with them then stand completely still (but don't stand too close) as their split shots can't hit what is right in front of them.
B.Licker
"Attaches itself to other B.Lickers, erratically moving around the room. However, if one of the 'segments' is killed, the others will be seperated"
Tip: Stay far from them and try to take them out by group.
Gurgle
"Slowly walks towards the player, shooting short-ranged but accurate explosive shots at them."
Tip: Keep moving far from them and don't stay too close.
Boil
"Stationary enemy that shrinks upon being hit. Will quickly swell up if not killed in time. Firing multiple various-sized blood shots in medium range when fully swollen"
Tip: Keep your distance.
