3 new game settings! If you are learning basics of the game or just want to enjoy whole song without the fear of failure, turn "No fail" option ON (your score won't be saved to leaderboard tables though).
If you just need to take things a little bit slower, adjust brand new "Song speed" setting to 90% (there will be -10% penalty to your score).
If you are already a pro and want to spice things up, turn the speed all the way up to 150% (you will receive +20% score bonus). And the gameplay becomes quite hilarious as a side effect, see for yourself :-D

If you want to focus on achieving the highest score, you can now setup "Score per hit" display to show just accuracy (ACC) or just power (POW) of your blows.
