4G decided to just stop developing this game, just before the final update, and as soon as he started working on his new steam game. You are all getting blue balled so hard!
Useless machine: the game. You are essentially encouraged to both have the most powerful turrets AND buy monsters for the smallest price possible, ensuring you are constantly at war with yourself xD
Do NOT violate the sacred number of endings: 1E308, for the limit was placed upon us by the gods of endings to prevent the great tragedy of the poop sock!
The profit initialy sucks so much due to operating costs and fines, that the only worthwhile investment is to put all your money in the bank...and if you take ANY loan, you permanently screw yourself within seconds!
try reload once after the update,
