Okay just played it. I think we may have another hit on our hands (thought only 10 minutes of play since it's way late here).
It plays pretty smoothly. The art looks gorgeous and it seems there's a lot to equip. Big plus that everything you can equip is shown in game. There's helmets, body armor, shields, and swords. And did I say I love the art?

Music is also pretty snazzy.
What I like about this over Block Legends (they're actually quite a bit different but have a similar look) is that there's more battle animations and I don't feel "rushed". I feel like RPG games shouldn't have a rushing feature in them.
I am a bit confused about what stats are what in the level up screen but I'll play some more and add more impressions later.
Btw, there is a heart timer and extra currency to open up chests and other stuff but we'll have to see how that works out. It does seem that regenerating takes a long time. I forgot how long since I last played but the timer reads that there's over 10 minutes left so it must be higher than that.
Edit: There's also a really cool feature where you tilt your device horizontally and you can see really detailed player stats and maps stats which I love (stat tracking imo increases game longevity). However the issue with this feature is I 98% of the time have orientation lock on so I may not use this at all since I'd have to turn off orientation lock just to see it. I wish they had a button which would switch to stat mode manually.
