Testing this nice little game, I am having some fun.
It is nice to test different way to (un)safely go through a building, yo uhave a lot of tactical options available.
Of course, depending on choices, the required time to finish each mission might vary, and you have a target time to reach to have all the 3 stars as score.
The game is still in development so the fees are progressively going up to match the final retail price.
For now, in beta, the game is sold for $15 instead of $20.
