Really enjoying the game. Glad to see someone following AdCap and making a true idle game. I get why you changed the creature names, but I did like being reminded of those old school MTG cards.
Gold Per Second should be on the main screen, not hidden away at the bottom of stats. Maybe switch the locations of Hero Souls and Gold Per second. Hero Souls isn't really a stat you need to know on any regular basis, while how much gold you are making on a certain lvl is something you always want to know.
