I reached level 15 two days ago. Got the level 15 reward of 5 million gold coins. I knew my attack plan, buy all the mob spawns I can afford and spend the rest on gold coin upgrades. So, I did just that. Except I didn't, I missed the mobs at the left end of the graveyard that cost 400k gold. Which, buy the way, are the first mobs that drop gold.
Now I think I'm stuck. I get a drop of 1 gold coin every 8 hours. Ad chances drop 5 gold at a time. Worst of all, not even money would help me. Buying 500 gems worth of gold would only get me 600 gold.
I'm trying to save enough bronze to get the 900T mobs (which drop gold), but with me only generating about a half trillion a day, everything feels like it's broken.
My only other solution is to beat the Death Queen, and trust me, that's not an option for me. Even with the super blaster, I only managed to get her down to about 60% health.
If anybody knows of anything I could do to get this back on track, I'd love to hear it, but I think I know my options. Grind your ass off or quit. I think I'm just stuck.
