Playing area doesn't fit on screen. Also is ALL of the game available trough play? Or is it pay to play? Bank upgrades and stuff you cant earn even in a million years grind? That would be a nono for me. Make it crazy hard to obtain I understand (ex: 365 day login bonus or whatever) but having to pay must be strictly optional.
Just started playing a couple of days ago, great idea <3. I would suggest adding a spawn MAX button to the graveyard that checks the current energy generation. That way if I use "Energy charge" item i can auto spawn more collectors / harpies. Will play more and see if thats a dumb idea to begin with :)) Once again great game!
