Overall it's a great flash game, but there's a huge issue with completionist gameplay.
Because the guards move randomly, it's almost impossible to get the under 30 second award in some levels, and the paths are irritating.
This has the hallmarks of a great game: easy to learn, hard to master. But I am not a big fan of the fact that the goal can only be open after the alarm has stopped, and that guards' vision changes as you move. It's disorienting.
Great. Simple graphics but wonderful gameplay
