This screams 'Cash in'. This is only a 'lite' version then you have to buy the app for an extra 99 cents (best; a 'special launch price'), to get up to 100 levels, which, without purchase could easily just be another 60 levels. Then after those extra 60 levels they are expecting you to pay to then download another 300.
Yeah, I don't smell anything dodgey here. I'll go back to my much longer apps which come with more for regular price (I.e. Kingdom Rush)
@wafwafer It gives you bonuses. You dont gain any extra playtime or anything from them. Your not competing against anyone, only the game. It may help you win, but its not needed, you get a large amount of cash from playing. Stop whining.
