★★★★★Fun and relaxing
This game is simple but great! It’s fun to watch your weapon selections play out, work together and do their thing.

★★★★★Horrible cards selection
I feel like the game recognizes when your doing good so it will purposely give you the absolute worse cards and weapons at first so you cant get what you want to…

★★★★★Manipulative practices
Beyond the usual with these types of games (using RNG and circumstance instead of skill) the game has what seems like purposeful glitches/crashes.
