apart from ant power and machinery upgrade nothing is worth in the long run, and i stormed to level 100 in a couple of days and the thing is well beatle colonys are worth the most followed by engeneers
now with 2 50% off for travel upgrades i still need 54k beetle colonys and i just dont see that really happening
so far for travel as soon as i got poisoness plants under requirement i would be good to go, not sure if bug or intended, but now without plants to kill i might be here for a while
so regarding xp upgrades i wasnt clear enough in my last comment, i was wondering if you plan to add more long term upgrades like cheaper stuff, stronger teamwork, science boost(wich would be REALLY nice) etc.
what i really like about this game is that its not completely idle and most of the time you have something to do, to buy,upgrade or kill and i appreciate the effort you put in :)
you shouldnt allow deficit of raw materials, what i mean by that is if i produce 1000 iron i can make max 1000 steel because the current system is exploitable
iron is 1$
steel is 4$
producing steel in deficit still gives 3$ profit per unit and i feel it should be looked into
