Attack of the Creeps is a Tower Defense game. The goal of the game is to
prevent monsters from traversing the screen by placing towers which shoot
projectiles at them.

Each creep has several statistics – hit points, speed, immunity, and some can
fly. There are various towers – some can stun or slow enemy creatures, while
others are effective against flying creatures. The towers all cost money, but
killing creeps earns you this.

The creatures spawn in waves every several seconds, and to prevent them from
traversing the map you have to create a maze of towers. There are six
different screen layouts, of different shapes and exit positions.
