Monster Inn

Monster Inn is a variant of the arcade game Space Panic. You have entered a building with multiple levels connected by ladders, and it is infested with monsters. Armed with a hammer, you can defeat these monsters by bashing a hole in the floor, waiting for one to fall in, and then filling it up. Each level ends when all monsters have been dispatched. Bonus points can be obtained by bringing the cache of monster eggs from the attic and dropping them into one of the bottomless abysses accessible from the first floor. However if you take too long, the eggs will flash pink and eventually explode, ending your game.

Each level becomes more difficult with increasing numbers and faster monsters. On later levels, you may have to escape by activating the warp box. This will randomly teleport you somewhere else in the building, but might lead you into even more danger. The game is over when all three of your lives have been taken.
