All twenty-five of the game’s levels are unlocked, which is good because the game is very challenging. There are some interesting rules in some levels that restrict what kinds of buildings can be placed. Your goal is to protect the hotel lobby from enemy units; rooms are placed in a freeform manner around the base. Rooms can provide income, shoot bullets or mines, heal surrounding rooms, freeze enemy units, or instantly explode nearby foes. Despite its short length, the flexible construction and chaotic pace of Bad Hotel make it stand out in the tower defense genre.
