Blagger is one of three new games for the Electron from Alligata Software. It has twenty (yes, twenty!) different screens, each with its own title and level of complexity. It will take you a long time to get through the first few screens, but persevere - it's well worth the effort.
The object of the game is to retrieve the keys to a safe. Once all the keys on that level have been found, you can open the safe and proceed to the next level. There are a number of lifts and conveyor belts that have to be negotiated, as well as a host of different creatures to avoid. The game is very simple to operate, needing only three keys, and is an excellent example of its genre.
