Yeah, I suppose I should have checked more before making decision.
Then seems like you should ignore my suggestion about buying energy after a few time warps - it seems like energy won't be too much of an issue, so might as well just go for the time warps forever.
But anyway - if you actually plan to play this, I highly suggest you do the 'free' 40 diamonds thing or wait for game to launch for extra 20 gems, because you only get around 93-95 free diamonds by the time you hit a major roadblock and unless you plan to spend inefficiently, you need to save up 100 to beat it in reasonable amount of time.
