WAKE UP N’ LOOK AT THIS

(SUMMARY AT THE BOTTOM) Hello! why is this so F2P?? I LOVE IT SO MUCH so basically getting this game was probably the best thing ever, as it might be the only gacha game I am able to commit to and still have fun. This is heavily F2P but sadly we still need to skip banners just for more characters, but it’s very manageable.

I got this game yesterday and would have had it on release but that does not matter. anyways I have probably put a couple hours in this game maybe 4 again I don’t know but I already have 62 pulls from playing including: 5,250 crystals and 30 limited anchor pulls or whatever. and it’s still fun.

because I used to play E7 (Epic Seven) and I never got anything because I just couldn’t help spending every single pull I had with no luck as-well as not committing to it. But this game has teaches me to not spend every single pull and to learn rogue-like + card decking gameplay. And it’s still very fun. So this is a very must try game,

and the summary if y’all are to lazy is: Super F2P friendly, great character designs, awesome story, and overall easy and fun. Its basically my limbus company.

One of the better mobile games

Lore is refreshing, i only wish they add more male characters. Combat is AMAZING THOUGH

Unique

This game is amazing and I find myself liking it much more than other gacha’s. It is very unique with the combat system and I actually enjoy it a lot, usually i skip battles in games like this but I actually enjoy the deck building and synergy this game has. Good work

Love the game, hate the summoning

The game is fun and great to play. There are plenty of things to keep you occupied and the battle gameplay is unique and engaging. Building teams and tackling events and bosses can be an entertaining experience similar to other games of the genre. The artwork and animation are pretty high quality and I enjoy the overall design of the characters and game world. Honestly when it comes to the gameplay and offerings, I have nothing bad to say.

Enter summoning. TO ME, this is a nightmare. My play style is a collector. I enjoy getting the characters and building them as best I can with minimal financial investment. However, in this game, I was not able to do that which ultimately led to me deleting the game. I was a new player who joined at a good time because there were several free characters you could acquire easily. I did that and even lucked out in getting the seasonal hero Heidimarie. Love her look and kit! Since then, summoning has failed on every banner, every time, no matter what I was summoning for. Hard pity has been the standard for 3 straight seasonal banners, 2 straight normal banners, 2 straight partner banners, and even the banner that restores motion to your cards consistently hits pity. I’ve played various game modes to stack summoning currency and even spent a little cash, but none of it helped. Reaching to the bottom of the barrel every time I summon gets old very quickly. I don’t want to play a game where I feel defeated just by opening the summon screen. That’s why I don’t play anymore. I hope this is helpful, the mods fix the summoning system and the game continues to prosper. Best wishes and happy gaming.
