About this game
Abilities & Items, based on child logic
Poison bullies with a pair of Stinky Socks, set creepy toys on fire with a
Magnifying Glass or make them step on some painful Pego Bricks!
And since all abilities use cooldowns instead of ammo, there's no need
to save them for later.
Tons of unlockable outfits with unique playstyles
Dress up as a Pirate, wielding a flintlock pistol and a cutlass for
close-quarters combat. Or maybe dress up as a Magician and keep your
distance, while your deadly bunnies do the work for you. Every outfit in
Billy's Nightmare starts with a unique primary ability and a more
powerful secondary ability.
Fast mounts for exploring
Since you can't run very fast in a nightmare, every outfit in the game
comes with its own mount. As long as no nightmare creatures are around,
Billy can use his mount to travel faster.
Friendly combat pets
Fire-breathing dragons, snowball-throwing yetis and barking dogs. Find
the Pet Shop and adopt a friendly pet that will help Billy in his nightmare.
