Ah yes, Sekiro, the universally beloved fetish deckbuilder??? Bold comparison.
For clarity: this game is a roguelike deckbuilder, not a AAA soulslike, so things like 'input timing' and 'grind' don't even apply.
I'm not sure if you actually played through the tutorial, but if you did, and actually paid attention, you'd see that the starting characters are perfectly capable of beating the current content, some easier than others.
As for Discord, it's not a cover-up, it's where bug reports, balance polls, development teasers, and suggestions are posted, in plain view. You know... feedback?
So, if you've got concrete thoughts on the card balance, or anything really, by all means share them. If not, Sekiro will always be there to scratch your itch for fetish oriented deckbuilding games?
