This series of games have always been the worst... My five year old found the first one boring and they have only gotten worse... why are will still being subjected to this garbage??? Whoever writes these should become the head torturer for the CIA.
Addressing the "heal" problem!!! when you run into an ENEMY always click attack first before attempting to flee. this will restore your health to full before. If you attempt to flee without clicking attack first you will start with the health you had at the end of your last battle. Hope this helps! + this comment to help others!!!!
What's interesting to me is all the comparisons saying how bad this is compared to other TD games. You do realize that this game is now almost 4 years old???? Many of the TD games now on Kong referenced this game for how to make a TD! None of the Bubble Tanks games were easy. They were meant to be challenging! You want easy points? Go play a game with snails in it!
Friend me if you need friends for in the game. Having more friends of higher levels will open up more fishing areas for you. The in game friend system doesn't seem to work depending on what browser you are using however if you friend people on kongregate that play the game they show up in your in game friends list. + this so other players will know!
