Ok, I have bought the "infinite energy", which is 4,99€. I believe it to be an good price for this kind of games. Still, the game is programmed to sell all kinds of "virtual gems" and "upgrades". You can spend unlimited _real_ money with that. What is even worse, the game includes its own advertisement engine, which allows the player to "earn" gems by watching ads. The ads include tank battle games. The game is rated 4+. Do you want a 4 y o kid watching the battle videos when trying to get 5 extra "diamonds" for his car. The ads cannot be disabled. And even worse: the games of this developer are including very prominent and hard-to-miss "hooks" referencing the user to their other games. You get them even if you pay for "no ads". I would suggest to ban the gentlemen from the App Store. Kudos for good graphics. Been greedy is bad.
