How I do it with keyboard; Tilt head anti-clockwise about 10 degrees. Put left index finger on "space" and left middle finger on b. Right index finger on g, right middle finger on t and right ring finger on 6. I hope this helps with keyboard positioning c:
I'm not sure if it's just me but it seems as if the level 9 walkthrough doesn't work. I tried refreshing but the big red ball wouldn't steer to the right.
I believe it's a small Easter Egg or something (where you zoom out enough that you get to the end credits and everything is in reverse). To get the shortest time, you need the gun to kill the boss, otherwise you would be stuck in Limbo. So, acquire the gun like normal and once you get it, move outwards until you reach the end boss. Kill the end boss by shooting the empty spaces in the middle of each vertical side of the rectangle. The easiest way to kill it is if you stay in the middle of the top or bottom of the area. When the rectangle gets to where you are, spam in it's direction and if it charges at you, go to the opposite side. So bottom -> top, top -> bottom. I haven't counted, but I think it takes 20-30 hits to kill it. Once you're done, go back to the credits and gain a score of 2500~ points. You can gain the last achievement by running through the game normally but without the boss - unless you have refreshed.
Well near enough 87.5% of the songs with Guitars are mainly rock 'n' roll, punk and heavy metal.
Instead of complaining, tell us what songs you would prefer instead.
The wizard achievement is more than impossible.. I'm surprised it isn't the last achievement of it's category. You basically have to perfect "I Just Wanna Burn" in order to get the achievement.
