Was wondering if there was one anywhere? Or if anyone can tell me what level mine should be at presently in order to make cannon level 20 by the end? Seems as though the numbers don't pan out for us to make it on time. Seems as though something should open up up soon in an update or something to boost the numeric of cogs earned each day. Any thoughts and possible help is appreciated. Thank you and happy holidays.
