I’m about done

Look I’ve been playing this game since the day it came out, and today will be my last day. It crashes nonstop on pc, I can’t make any purchases they just fail every time. Unless I see something about it being fixed so I can get the new character fei I’m not playing anymore, I don’t have enough time in the day to grind for pulls.

Sts enjoyers assemble

Great mobile game if you’re into slay the spire or any deck builders. While it may not scratch the exact itch, it gets pretty close

more respectful clothing for the women

Honestly a great game. I love pretty much everything about it. From the rogue-like gameplay that gives u the opportunity to continue to make your characters better to the great quality of life. I really just wish they respected the female characters more.

The option to play on desktop is appreciated

One of the few mobile games I play that’s also on macOS. I’m happy get off my phone and save some storage. It plays fine from my experiences of far.

Decent Game, with a warning

Gameplay is fun and I don’t mind the grind too much. The story is okay, feels kinda messy. However, if you are picking up this game because of characters like Hugo or Kayron and only because of them…just leave. The game heavily favors fanservice, with their season 4 characters essentially being almost entirely naked. Completely clashes with the horror aspect of this game. Overall, really disappointed with the artistic direction of this game as of now and will likely be uninstalling in the near future as I really don’t feel seen as a player anymore. I know the devs are going to either not see this or ignore this review which honestly wouldn’t be shocking.
