Not going to lie, having beaten each circuit at least once, I'm...kind of unsure where to go from here, if anywhere. Collecting the remaining gallery options is extremely difficult (that bonus battle is extremely not worth it IMO), and actively discourages me from 100% clearing this game.
I think the game itself is neat, and is very cool in how it is designed, especially after the earlier balance patches, but...there's just not a lot of post-grind content as of RN.
Also wish there were more "extreme/hyper" options for who to go up against; At most, I've dealt with someone who can get up to four uses of BE on them, and that is good, but I wish there were more of them.
