Oh Mummy is a remake of the classic game from 1984 that some may remember being bundled with many new computers. You can download all 71 of the Crozza Remakes here.
Oh Mummy has you trapped in a tomb trying to find your way out while mummies chase you around. If you discover a mummy, it will follow you to the next level. In some way, the game is similar to Pac Man. Footprints are left behind as you walk, and once you've uncovered the required items, you can exit to the next level.
F4 will switch from full screen to windowed mode. Arrow keys to move and it takes a bit to get used to turning correctly. H for help, P for pause. A joystick can be used and is recommended. Like all Crozza Games, the game is portable, so no installation is needed.
