Fun enough initially but pseudodifficult and frustrating
This game has a problem that many roguelikes share, which is that some of its “difficulty” arises from the statistical risk that it might generate a board which is impossible to beat even with perfect play.
At lower levels of difficulty this is acceptable because it’s reasonably rare, but in some of the game modes, and with some of the characters, particularly the extremely imbalanced/gimmicky ones, you’ll find yourself losing because of an impenetrable wall of damage that no amount of preparation can forestall. This is frustrating.
The counterpart to this is that the RNG sometimes produces games that are arbitrarily too easy, even at a higher difficulty setting. Victories achieved this way are unfulfilling. That feeling of unearned victory bleeds over into a suspicion that all of the victories were due to flukes.
The interplay of the various game item cards encourages a range of play styles and makes each character feel unique, which is nice. The corresponding downside to this, which I think others have pointed out, is that you are often at the mercy of the RNG and you will wind up often using one or two default strategies based on the first couple items you happen to get.
Overall, this game is not particularly difficult. I got to 100% completion on this game in about 3 weeks of casual play.
I like the game’s visual style, and it has a fun dungeon-crawl-throwback aesthetic.
