34 seconds to play, wait 30 minutes for "energy"

The "energy" limit on this game is a complete BS...
I have finished this game to the end 4 times. I had to install it on 9 (NINE) Apple devices 4 apple IDs so I can play at least 25 minutes on all of them together. I run out of energy on one go to the other iPad/iPhone. So, heres how it goes: the MAXIMUM energy is 310 (and thats MINUTES you have to wait until you can play again!!!)
Each stage lasts about 32 seconds and each stage requires 30 minutes of wait. So... 300 = 10 plays, total of 320 seconds!
