Your finger is the flashlight. Pop cute ghosts, set off chains of light, grow a big tree of upgrades and bring a haunted house back to colour, room by room. Your finger is the flashlight. Drag the beam across a dark room and the ghosts start to glow. Hold it on one long enough and it pops, throwing sparks of light at every ghost around it. One pop sets off the next. Chains of x10, x40, x70 light up the whole room at once. Every ghost drops ECTO. ECTO grows a big tree of upgrades: brighter bulbs, wider beams, prisms, helpers, a magnifier for the sneaky ones. Each one changes how the next night feels. When a room is cleared it floods back to full colour and stays that way. Restore the house room by room, floor by floor: the ground floor, upstairs, the cellar and the attic. Watch out for BOO, who jumps at you, and catch the Golden Boo if you can. An active incremental: you hold the light, nothing plays itself. Short nights, real progress every time. - 24 rooms on 4 floors, 4 bosses, and a FULL MOON after the end - 76 upgrades, over 300 levels - Pixel art, one thumb, upright Free to play through the first rooms. One purchase opens the whole house. No ads, no timers, nothing else to buy.
