Very nice game. But: Absolute battery killer!

The game has an admittedly simple but chic and functional graphics and a quiet and unobtrusive soundtrack that is best enjoyed on headphones.
The game is great fun and ties (me) for a long time.
Control goes well out of hand, really a first-class 5-star candidate.

Why I forgive but still only 3 stars?
First of all, the game seems to be extremely resource-intensive.
My Galaxy S2 (not G-model) is extremely hot during the game and reached peak temperatures of well 55 degrees.
In addition, I previously had no app that has sucked me as soon as the battery is empty the game.

Especially noticed was me that when a battery level of just over 15% the attached original charger was not able to fight with running game against the battery discharge. While playing, I suddenly got a warning that the battery charge is only 15%. The battery charge is therefore removed despite charger connected while playing on.

That is a different way, can be seen in games like World of Goo, which hardly the battery charged during long and persevering games.

When traveling, the game for me is nothing. Would play after grossed approximately 3 hours my (large) 2.000mAh battery are 100% completely leergelutscht.

Nevertheless:
From game principle I would recommend this game definitely.
