Don't give up. Just like stated above in the tip on how to get the hard badge, try and try.. Keep trying but don't stick in those instructions too much. Simply the best way to avoid several stuff is to stay in the right bottom corner. Flashers, V format pixels, eventually they don't touch you there. The best way to beat the game is to practice. No theoritical knowledge can help ya there, just keep practicing. Did it in about 10 tries or so. Got the hard badge.
The Heart Rate function doesn't quite work. There are times when I press the action very hard (3 hearts) and I get around 3-4 chances during the match and then I choose a slow pace (1 heart) and I get more than 5 chances. Guess these options need to get sharp and get fixed.
This game is the perfect example of how to put FUN in a game and don't make it boring one bit. Great game. Couldn't hold laugh at certain times. Really exciting and a fun game. Thumbs up if you want a sequel :) I do!
Thanks!
