I believe so. I can’t have 450 HP without full upgrades, right? I think you need to clear all rooms to have enough points to trade for 450 HP, which include all upgrades rooms and gem rooms. And I do have 450 HP now.
Yeah, some easier modes would probably help more players to enjoy your fine work.
I must confess that I actually, um, cheated many times——by PRAYING that I can finally get to the next save points, after dozens of failures;) (following play to win and pay to win, now we have pray to win here!)
Thanks for putting your love into making this game!
