8 hours in and I'm pleasantly surprised with this game after hearing mixed reviews when it released in Japan. I was most worried about 15 item limit and no targeting in battles but so far neither has been an issue.
I keep the inventories of my party members as clean as possible and make sure to drop things off I don't currently need in Item Storage (thank god this exists or it would be a lot worse). Targetting seems to work just fine. My characters seem to attack things intelligently as well as healing. I have seen some odd heals once in a while but have yet to die because of one.
Crowns (Hats/classes whatever lol) are a really cool system so far. There are a bunch of different gems that drop off enemies and each Crown has a pattern you have to fill in order to level it up and gain a new ability. Apparently each Crown has 3 levels so you can get 3 new abilities through this method. Of course, the 2nd and 3rd upgrades are a lot more complex and require more gems. Speaking of which, you don't get money from battles at all (well so far at least), so gems are the way I have made mine. A little farming in a dungeon and I've got enough to updgrade my people - cool system, and later I think you use gems to upgrade weapons and armor, making decisions even more hazy in regards with what to do with your gems. Also, when you get new Crowns, everyone can use them, but you have to upgrade them for each individual. I was surprised to see this, but I guess it ties back into the whole gem mini-game as I like to call it (always deciding what to do with which ones).
Managing equipment on characters is a bit cumbersome. There are too many button/stylus presses to get into the screens for equipping and moving items around between party members. You will also find that you NEED to equip certain accessories or weapons with effect at different times so you will have to change to the new stuff and place your other things in storage. Then later, you have to go change it all back out and equip again when you are done with the circumstance-specific things. This isn't a dealbreaker for me but it definitely could have been handled better.
Music is wonderful! It changes dynamically at night and in battle when you are low on health. The tracks are a bit on the short side but have been really catchy. Day/Night cycle is INSANELY fast. I mean, walking around on the overworld it's seconds from night time to morning. This is a bit jarring in the beginning too but something else I got used to.
I would say to anyone that has been on the fence because of the inventory limit to go ahead and pick up the game. Even targetting is fine. I also hear the game falls apart in the later hours but it has been a blast in just 8 hours and already worth the purchase for me.
