I've never played a game like this, I am a newbee. I have to say it's too difficult for me. I never survive more than 10 seconds in a single game, and if danger arises, I don't know how to react. What is the objective of each level? Is it simply to survive and get out of the tunnel?
Could you please display the map and toolbox by default, reducing the number of keyboard shortcuts players need to memorize and use?
I will give 3/5 star for this game.
