suggestion: a magnet minion, it flies around the map (not following you) and collects money with increased moneycollection range when upgrading magnet or insted of it roaming the map you could put it in a place and it always collects money from that specific spot? Thios would be helpful for when you upgrade weapon to homing missiles because you can't always get all the money and it would be good for bosses when you can't get to the money as the boss is in the way. What do you think?
Epic Combo 2! could be: customize hammer/suit, able to delete weapons you misplaced/ don't want, able to go to shop without timeing out (use manual timeout button next to the timer instead) and customize turtles! everything else is epic enough already!
