So I don't know if this bug has been reported, but I've somehow managed to make the Meteor spell deal negative damage, causing enemies to gain thousands of HP every time I cast it.
I am not sure what could possibly be causing this.
Edit: Took a cursory glance at the thread and want to second the fact that the combat and progression feels really grindy. The combat in particular is really simple, but not in a "simple with engaging depths" way. Just in a "it's really easy to crack the best move in any circumstance" way. And moving through the Slay The spire type map doesn't really provide enough interesting variation in choices, especially when what you choose often feels less important than what the die roll says happens afterwards. I almost feel like I'd rather this play like one of those minimal/no input gacha battler type games. Those games, when executed well (or at least, as well as they can be) are mostly about acknowledging their systems aren't that deep or interesting, and that most of the important choices are made before a combat even starts. This game feels similar. The combat is less important than how you invest your resources, which is the part of the game that feels both more strategically interesting and more rewarding. Having the combat/dungeon delves be simplified and quickened and involve less time and input on the player's part feels like it would be a smart move. Maybe a suggestion that's coming way too late in production to do anything about, but possibly something to keep in mind for future games?
