----------------------------4.3 Time Attack Driller--------------------------

In Time Attack you try to reach the bottom of a cave as fast as you can. Just 
like in Pressure Driller you only have one life, points do not matter and you 
can choose between all characters.
In order to balance the different movement speed of the various characters 
(Usagi is not playable) there are different time limits for each driller to 
beat.
As Time Attack is the only play mode with non-randomly-generated levels every 
level has some path you're supposed to take for the fastest time but often 
there are different options to take and you have to try out which way is the 
best.
In this play mode the air supplies are infinite and the air capsules as 
essential item are exchanged by clocks which stop the timer for a certain 
amount of time.
Furthermore there are three Time Attack-exclusive collectibles that affect 
blocks (see 3.3 for more info).
After beating every normal level you unlock the reverse courses which are 
just mirrored versions of the normal levels with a real bad-ass time-limit.
Since both kinds of levels basically have the same layout I'll "only" give 
you a guide for the normal versions but with solutions that will also apply 
to the harder reverse courses times. So when playing the reverse courses just 
change any "left" to "right" in my guide and vice versa.
