Collect all coins in 10 seconds. Special blocks are added each level.
IMPORTANT: the keys 'V' and 'B' allow to tweak the 10 seconds limit (and
thus the difficulty). Search an efficient solution (ignore the timer
limit!) and then try to re-execute it in time.
Controls: arrows keys (or WASD) to move, 'Space' to retry, 'Return' to
go back to the first level. 'M' to mute all sounds and 'P' to mute the
timer beeps.
There are 10 levels and after the end, the game restart with an
increased difficulty (-1 sec). All levels are doable in 8 seconds.
