The Attic Monster

From BoardGameGeek:

Four friendly ghosts lived in their big old mansion for centuries. They had tons of fun scaring and tricking the villagers and throwing their cute but, of course, horrifying parties. What a wonderful afterlife! The ghosts loved inviting guests, but not every one of them was so grateful for the invitation… A creepy Monster decided to have their mansion all to itself, so it kicked them out and nestled in the attic to play the ghosts' favorite video games non-stop. The little ghosts need your help! Together with them, you will explore the graveyard looking for keys to the rooms and the attic, find your way around traps, accumulate power, and then use it to get their sweet, spooky home back, sending the ungrateful Monster to its world. But be careful! The Monster becomes more powerful every round. Throw the dice and think through all your moves together!
