Great game 5/5. I don't like the idea of being forced to follow developers twitter or joing their facebook fanpage if willing to max out the game though...
which level is supposed to be the last one in non-premium version? Asking because haven't noticed any ending after beating the last level possible to play...
 "Kingdom Rush Frontiers"){kind=icon}
 "Giants and Dwarves TD"){kind=icon}
 "Tesla Defense"){kind=icon}
 "Kingdom Rush"){kind=icon}
