I've been playing this for a few hours and all I want to say is please, please, please either give us the option to purchase the full game and get rid of timers, or increase the amount of energy/decrease the amount of time it takes to refill. Or even add the option to watch an ad or two to refill the energy.
This game is awesome and I can see myself playing it a lot, which is why I would like to play it for longer than 5-8 minutes before I have to wait 1 1/2 hours to play again.
I would be happy to pay for a full version if it meant being able to play it without, or with less ridiculous timers.
I'm spending more time being annoyed about this than actually enjoying the game.
