Since I'm not a native English speaker, my knowledge is still not wide enough to discuss about the word problems that appear in the game, so I'm just gonna mention some of its main good points. I've totally been knocked down with the way the whole game works. Not only this game itself is an extremely addictive one, but also I've never faced any annoyance during my experience with it till now. Coin purchases are available but no extra level purchase, play the game and you'll get coins for unlocking new levels. Advertisements do appear sometimes, but as long as they appear neither too much nor always after a single level completed, I'm totally fine. Furthermore, although a lot of pp said that there were vocabulary mistakes, I still haven't had to deal with one ever-since I started playing. This is why I'm not gonna regret a full stars rating for this game. Keep on the good work you developers! I'm excitedly looking forward for new levels to solve. Love xo.
