I dont know why this game isnt more popular, super free to play friendly, the ads are completely optional and if you do watch em they reward you in kind. Nice variety of characters and enemies, if you are free to play like me or dolphin you will enjoy the strategic aspect of the game, it is engaging to collect more characters and see how you become stronger and better at the game, even as a free to play, really a fun experience

This game is generous with rewards, especially for events. I like games where you have a team of heroes and the strategy lies in the timing of which heroes you use. First game I played like this was Seven Guardians of something, which later was cloned as Seven Hearts. Only they did it better. One thing that is unfortunate is clearing a map is all about speed, so run speed is way too important. For many maps the only thing you need is one good rogue character w/fast run. Too linear.

Game has unique character designs and content. Very fun mechanics to learn and master. For this genre, it's lacking quite a bit of in-game information and QoL functionality for players that make actually playing the game quite frustrating. Progression is not very balanced. Resource gain is very difficult and hard to grind for. There are 3-6 ads for a single 20-30s battle... The P2P aspect is huge, literally chunking of entire swathes of content. Power-creep of new heroes is huge.
