Version 1.1 is now in game. It includes 2 new levels, showing picture of map before playing it, extended version of bonus level 1, so you can play against all enemies on 3 different maps and each on 3 modes, depending on with how much money you want to start with, and also I did a little bit of rebalancing tower (changed costs for 4 upgrades, at least I don't remember making more changes in these days).
