Hello. I checked this game and i liked it. Buut.. i have couple suggestions for dev, if he ever open this thread.
1 - Possibility to use captured succubuses in combat. Sure, after some attuning-type quest or using some catalyst, sort of option. These are tough bitches in combat, specially if accompanied, why not?
2 - Option to sweep/skip/autowin nonchallenging battles. After ~5-10 sequential wins by selected deck or after ~5-10 sequential wins on next tier battles. I found quite tedious and grindy to catch cards.
Other than that, game has fine story, girls and overall content. Im interested. Will follow.
