Summary:
-A very solid, strong game for 20 USD, with 30-60 hours of challenging gameplay.
-UI is crisp, gameplay loop is clear and engaging, and there are quite a few build paths for decks. Art and music are amazing and very cohesive.
-Let the game stand on its own: anticipate needing tactics and careful positioning and itemization to win. Do not expect to play Slay the Spire. They are different titles for a reason, and therefore bring something different to the table.

Addressing a few other reviews I have seen, at length:
-There is ~30 to 60 hours (or more) of content to fully beat the game (as of the time of this review). I think that is more than fair for 20 USD. More content in the future would be welcome. (Deeper card pools after 'initially' beating the game, or additional Hades-esque Heat levels.) Not every game has to be a best seller, top-of-charts game for you to have a good time, and this game delivers quite well.
-Games are designed to be difficult, but beatable. Like any Rogue-like and deck builder, there is a tremendous amount of player agency. This game does a VERY good job at pacing when new enemies and new cards are introduced, such that the player eventually is exposed to the full array of cards and foes they can expect to run into in a reasonable, but not unfair, time frame. If you lose, it is because you mismanaged resources, or forgot that 'Aimless' actually reads 'Kill Target Player'. ;)
-Do not anticipate this game to play like other games you may be familiar with. StS , Monster Train, what have you. As a long time MtG player (+Shadowverse, Lophis, Hearthstone, Ashes, Star Realms, etc) I am familiar with varying takes on how card games and deckbuliding games operate. You should not expect every game to operate along the same axes that games you already enjoy. Yes: Wildfrost is a 'deckbuilder'--provided you think of picking your companions and supporting spells added to the deck as building an entire deck. Crowns let you effectively "First Five" Companions/Clunkers/spells that you think you will need, which is already significant departure from how many card games operate. To win some nail-biter fights, you may need to sacrifice your entire roster of Companions, which are then injured.

All this to say: let the game's mechanics and gameplay speak for themselves. It isn't for everyone, but no game is. To compare it directly to the other (voraciously popular) card games in its genre is a disservice. If you want to play StS, just go play StS.
