First: If you like Legend of Zelda puzzle elements and action-based combat, you'll already like this game and get dozens of hours out of it. lots of side quests that actually have pretty lengthy stories on their own.
lots of cool and cute character designs. The 5* characters definitely feel more anime in their attacks than the 4* characters, but I've enjoyed all of them, so far.
Gacha system actually makes it pretty easy to get several characters you like, free, for new players. That makes it much easier to keep playing to either earn or, if you want to support them, buy additional ones.
Tough out the intro at the first city. Its well worth the exposition.
There's a ton of exploration content. There's hours and hours of content that's free. Resource gathering will easily get you through any early grind (which there really isn't up to resonator level 50) especially if you gather stuff, here and there, as you explore. I havent paid anything, yet, I've had the game 2.5 days, and I've gotten 20 hours out of it. Because of that, I'm probably going to buy something to support their awesome system. Like, if all Gacha games were like this... I'd probably love gacha games.
Is there an energy-based limitation? EHHHHHHHHHHH sorta. Its only for upgrade materials, and Its actually a more forgiving system than FFXIV's daily dungeons and trials. Rather than a few times a day for weapon and upgrade resources, its a a few times a day plus it regens while you play, you can explore to find more of the energy, you start with extra... i mean its a pretty solid system.
And yes... you can pet some of the cats. I haven't found a pet-able dog yet (lots I cant interact with, though), but I bet there's a dog I can pet, too.
As far as bad stuff... I'm probably going to have to update later for anything more than nitpicks because nothing has been badly designed, yet. Not... to me, anyway.
Nitpicks - A graphical bug here and there, missing sound effects in some cutscenes, misplaced 'he' and 'her' for the main character based on which Rover you pick. (like the female Rover being called 'he' and 'she' in the same cutscenes.)
