Oh well. I've done a LOT of mistakes. One of them was getting to 27 energy collection without a single storage unit. I think i could do it in less than fourty minutes on a second try, but...
If i was not completely exausted after work yesterday, i would've posted by then.
But I do not regret double speed. for me its double the fun at the cost of high scores. Meh, hit me baby one more time.
