This is for v0.8.0
The game is WAY too easy.
It's basically a lose to win game, but you really have to want to lose to be able to lose.
I just finished a playthrough of current content and only came close to losing once and it was purely because of poor RNG on the card draws for a single battle against the strongest enemy in the game.
There's also no saving function as far as I could tell, so be prepared to start over if you leave the game I guess.
Thankfully, the game is incredibly short if you never lose, so a save function isn't really necessary.
Definitely an entertaining way to pass the time, but the degree to which you have to try to lose is insane.
If you want to see any content at all, then never level up your abilities, burn all of your good cards, and intentionally play losing cards whenever you get the chance.
There is no gallery either, so the only way to see content is to intentionally lose.
EDIT: Apparently you keep all of your levels from previous runs when you start over, so definitely don't level anything up if you want to see any content. It apparently only saves run data as long as you don't close the game.
I made the mistake of maxing out my luck and strength in the first run so now I don't even know if I can lose even if I try.
