Ok, after being in lvl 16, had beaten the arena, had the best upgrades and items (even though I coulnt equip them) my save data is GONE!!! my rating is going from 4 stars to 0!!!
There is an error when trying to conquer to make a vassal "Operation alert !!!null!!!" Please fix AND as other players have said. Decrease the time for upgrades for higher levels. It really makes the game less enjoyable , there is a drastic gap in the time you can spend upgrading your city and your troop, suddenly an just one upgrade leaves you on a long wait, and gold becomes scarce, so you can't compensate.
Its a shame that Learn To Fly 2 has a better rating than this game. They are not even comparable... It just proves most people are interested in shallow and dumb games.... Not that Learn To Fly 2 can't be fun, but I think it is not 1/10 the work done by xdanond making this game. Its pathetic and its a shame....
Here's a tip. Just concentrate on the platform to the right. Focus on jumping right instead of watching the monsters, if you see something black close eyes.
Do enough achievements to buy the first premium weapon. Is the best accessible weapon without having to pay for diamonds or finishing the game. The last row of weapons sucks.
