Seriously, if your boss or your fans is not happy with you cos your shot just went astray or get collected by the keeper, the only two players that have positive fan relationship in this world would be Lionel Messi & Christano Ronaldo
Hmmm......after so many residents got killed(squashed), the gummy bears are still not willing to give the wallet back to Biston to get rid of him. I guess the president of gummy bears is condemned and he will probably be overthrown in a few days
Actually the tower completes in 7 floors, though the game doesn't tell you.
My suggestion for survival mode is Skeleton, Reaper, Soul Jar, Confusion, and 2 other power you find useful. Also the 3 upgrades that worth 1 scarabs.
Skeleton & reaper can constantly kill with a small consumption of mana, you only have to recast maybe once 2~3 minutes. Soul Jar keep giving mana to you while killing the minions, just make sure you don't smash the jar without hitting any minion. Confusion can slow the minions down, despite making the warriors to kill their allies, so it is useful in gaining time.
I personally would also recommend fireball, which costs the least mana and have the shortest cooling down time, but the 4 powers above are my doubtless choices
