I don't know how many people know this, But if you click that little Sword icon on the main menu, It turns on hardcore mode. I've never noticed it before. I guess I am a bit slow.
I think some money bonus or unlockables would be a good addition to the trophies. It would give people more of a reason to work for the trophies. + If you agree. Also, 4/5, 5/5 After updates with glitches.
Wow... Even Knowing this is just a game i felt pretty bad shooting apart the heart and the end. Over 17 levels i started to feel a bit attached to the robot.5/5
