lost my account :(

I played the game since launch day and stopped playing for a while and was logged out of my account and lost everything I do still enjoy the combat and visuals but I just lost all my progress

Review.

Game’s good, no complaints aside from one.
PLEASE STOP MAKING PLAYERS USE YOUR PREMADE TEAMS. THEY ARE USELESS, WORTHLESS AND HAD NO SYNERGY BETWEEN CHARACTERS. Base deck with nothing in it is simply pathetic to play.

Wow

Characters are too revealing, lets chill lads

Gacha + Slay the Spire

If you’re a fan of Slay the Spire or similar games, you will love this. The gacha aspect is also fun. Absolutely no need to spend money because all the strong characters are on the standard banner.

Game Improvement

As time goes on, this game continues to make improvements on gameplay and the time commitment required to play this game.

The gameplay is very good, and it’s a (relatively) healthy gacha system.
