Changes:
- "How to play" section now displays some hints.
- "Easy mode" becomes available if the mission is failed twice in a row.
I made these changes after noticing that some players really struggled with the game. The hints give tips on things that some players might have overlooked. Easy mode doubles the players HP and damage output on equipped weapons. It's optional and the only punishment for using it, is that you can't get the "Mass production miracle" achievement when on easy mode.
