Agreed, agreed... the key to the game though is to restart it... and restart it... and restart it-- each time pushing your "game Bonus" time multiplier up.

if you can get the "time warp" multiplier up by spending diamonds, that helps immensely.

Each skill takes more time to get... pushing the time it takes to gain them up exponentially... But the Multiplier increases as well.

If you can get a 100% increase with a restart, then you will find the game progresses very fast... getting back to where you were in half the time and progressing twice as fast.... that is until it bogs down as the time it takes to gain your skills gets silly again....

This, of course, is where the temptation to buy that little multiplier kicks in... just to see whats around the corner... which, of course, isn't much... but oh wait... look.. etc... and the time to increase your skills keeps on increasing.... days... weeks... months...
