nvm, I think it's intended since cards are starting to change after you go over them, and the cards ahead are getting stronger (ah I see what the food does now)
yes, it's intended. There are also rewards to get infinite mana that, with a nautilus let's you get infinite health too... which is needed for level 10 on hard mode.
Oh, and there's a soft cap of 99 for money, but I plan on adding a reward to remove it and let you probably also get infinite money.
Thanks for playing it!
