Six floors, six bosses. Enemies come in waves. Beat every wave and the door opens for the boss: the Big Skeleton in the Stone Hall, the Zombie Brute in the Crypt, the Skeleton King in the Throne Room (he keeps calling guards), the Conductor Skeleton in the Train Station, Chef Bones in the Giant Kitchen, and the Bone Dragon in the Bouncy Castle. Bosses shake before they charge and show a red ring before they slam. At half health they get angry and learn one new move.
The Train Station: when the bell rings and the track flashes red, a train is coming. It knocks out every enemy on the tracks, and knocks you back a heart if you stand there, so lure them on and step off. It hurts the Conductor too. The Giant Kitchen is a food fight: angry carrots and meatballs, and pies fly out of the pots. A dark ring on the floor shows where a pie will land. Chef Bones throws pies and slams his frying pan. The Bouncy Castle bounces. Step on a striped bounce rail to fly across the room. The Bone Dragon walks, flies, dives where a red ring shows, calls mini skeletons and breathes fire along a glowing stripe: get off the stripe! Beat it for the Dragon Crown.
Hero powers: each hero has their own on the POWER button or R. It recharges like Spin. Knight: Shield Bash, a charge behind your shield that knocks everything back, and nothing hurts you while you charge. Elf: Leap Strike, a big jump that slams down in a ring. Wizard: Sleep Cloud, a fireball that bursts into a cloud and enemies take a nap. Lizard: Vanish, you go see-through for 4 seconds, enemies lose you, and your next hit is a 3x crit. Grandpa is a knight underneath.
Camp: tap Camp on the start card. Mr. Hops the frog sells weapon upgrades (up to 5 stars, each one about 20% more damage), extra hearts, a bigger food bag, capes, hats and pet hats, and there is a cheaper deal every day. Every coin you pick up is yours to spend, and winning a floor pays a bonus. Every boss you beat gets a gold statue on your trophy shelf. Quests are small goals with coin prizes, three at a time. Finish one and a new one appears. Beat the Bone Dragon to open Boss Rush: all six bosses in a row, full hearts before each one, against the clock.
Move with WASD or the arrow keys, or drag a thumb on the left half of a touch screen. Space, a click or ATTACK uses your weapon (hold it down to keep swinging); a gold number is a critical hit. E or SPIN hits everything around you, then recharges; hit five times in a row for a combo and Spin is ready at once. R or POWER uses your hero power. Shift or ROLL is a quick dodge: nothing can hurt you while you roll, so roll through a charge or out of a ring.
Weapons: there are eleven to find, in four colours. White is Common, blue is Rare, purple is Epic and gold is Legendary. Every boss drops one you do not have yet, a golden chest pops up halfway through each floor, and now and then a skeleton drops one. Walk over the glowing weapon to pick it up. The Fire Sword sets enemies on fire, and the fire jumps to a friend. The Ice Hammer freezes them, and frozen ones shatter. The Lightning Staff zaps three in a row. The Boomerang hits on the way out and on the way back. Hold attack with the Bow to charge a big arrow. The Bubble Wand floats a skeleton in a bubble: hit it to pop it. The Twin Daggers stab twice. And the Banana makes them slip, spin and knock each other over. Pick what you carry in the Armoury.
Make your hero: pick colours, a hat, glasses, a beard, polka-dot boxers, or tap Grandpa. Pick a pet too: Dog, Cat, Dragon or Sasquatch Jr. Your pet follows you, fetches coins and food, and nips enemies. It never gets hurt, it just gets dizzy.
Coins pop out of everything you beat. On the Crypt and Throne Room floors two glowing statues are linked: walk into one and you pop out of the other. Chests and some enemies give food for your bag (up to three, or five with a bigger bag from Camp); tap the food button or Q to eat one for a heart. You have five hearts (more if you buy them at Camp); losing them restarts that floor, and you keep your food and your weapons. Kick the rubber duck.
Health packs are red hearts: walk over one and it heals a heart right away (if your hearts are full it waits for later). Enemies sometimes drop them, more often when you are low. Smash the pots, crates and coffins along the walls with any attack, or roll into them: they hide coins, food, two health packs on every floor, and sometimes a power-up. Power-ups float and glow, and a ring under your hearts shows how long each one lasts. The Golden Shield blocks the next 3 hits. Speed Boots make you fast for 10 seconds. The Power Fist doubles your damage for 10 seconds and your weapon glows red. The Coin Magnet pulls every coin to you for 15 seconds. The Extra Heart gives you a gold heart for that floor, up to 7. When the boss door opens, a golden chest appears with 2 health packs and a power-up, and the boss waits until you open it. At 1 heart the screen glows red and your pet runs to fetch the nearest heart or food.
