Hi,
Not sure if its just me since i did a search and no one brought it up yet, but the game seems to be draining way too much battery for its simplicity (no use of gps etc.)
At the current rate my iphone 6 would last about 2-3 hours after fully charged and the phone would be really really hot.
To be fair, i compared using daily functions like whatsapp, phone calls, facebook browsing and playing the game Otogi and COC and it would still last me a day (approx 8-9 hours)
Hope this reaches the dev!
