@randomusername1 well counting that by lv5 they cost 60k goo i dont think you would use them but they are very useful for packs and they also do 20k per bomb. they are your best friend if you can use them right.
best challenges are 3 heart runs and no gun upgrade runs. in my opinoin i like then 3 heart run the best.(tip) if you get a heart container, you just refresh the page and the heart container will be gone.
I really wish chris could add a friend list. in the energy shop there could be a way the buy more friend room. like 1 friend space=100 energy 5=300 10=800 50=2500 and so on. + if you agree. =)
how about a button where if your getting trolled you can press it and everyone gets kicked out. press it again to let them come back. this would help the makers so they can get rid of the trollers bricks
