I probably judged Vivid Knight a bit too early. I have played it a few more times with 2 more victories. The second character is decent and has different gem units to use for the most part. She plays differently enough. The harder and more gimmicky dungeons require more strategy too. The unlocking is very, very slow and grindy, but it keeps you playing. Honestly I'm getting more and more used to the gacha mechanics, and it's fun most of the time. You play percentages and gamble a lot to hope you can get certain gems and gem units. I love how in the beginning you're just trying to get something that could work and then you could try to get certain symbol combinations that unlock abilities. Rares become more common as you move down in a dungeon too, so there is a natural progression from wimpy gem units and gems to stronger rarity ones. The autobattler mechanics can be frustrating and confusing at times, but you get used to certain symbols. Overall it's a fun roguelike mixed with gacha for variety, with not as much variety in dungeons theme wise, but still fun overall. Upgrading my review from 7/10 to probably about an 8/10.
