What? We have to purchase something with real money for a quest? Aw, that's a big "wound" to my rating AND I can conclude that the developer is quite greedy.
I love this game but can you turn off the world prosperity? It gives too much exp bonus (in percentage) and makes me to level up too fast. Now I have too much to do because of it.
Research and regions that give reduction on healing time of units and heroes just make them heal longer. Usually, an infantry of Undead need 12.5 to be fully healed. But now, after research which reduce army healing time by 5%, it takes about 13 minutes for the same units to fully heal.
AARGH... Lost the game data. Now I've to restart it from scratch again. It always happen on every BTD game I play on Kongregate. WHY??? What's wrong with my computer?!?!
