So...I think I found a glitch in the game.At level 13(the Bonus One) somehow I was stuck in one of the gaps (where you were supposed to put the ball and then hit the rubber ducks) and put a portal on the ceiling part. When jumping into the portal,I found myself outside the testing area(the place where the buildings are). Is this a glich? If not, you should make the buildings touchable and there is one ladder that I think it would be interesting to climb,to the top of one building.
,,A mysterious and impractical upgrade that is probably not worth the cost"!!!! man i spent 3000 coins on something that isnt even real!!! damn it will take me a lot to get 3000 coins back!!!!!!!!!!!!!!!!
try clicking fast on the tanks and robots because if you click slowly or just hold you will see that at one moment the health bar will stop "killing" them
