Pretty cool game so far. Nice artstyle, really nice UI with good feedback on tap. In the beginning they give a ticket that you can use on a banner with 30 free rerolls, with what seems to be really good rate. I was getting at least 2 5* per roll. Really good that games are introducing this feature now. Making rerolling easier and more accessible for non-hardcore gacha players. Overall looks like a really good game.
PRO: 30x built in reroll system, turn-based combat that allows you to select as many attacks as there is AP (action points), and visuals that are very well illustrated. some 5 and 4 star characters can utilize special "Eidelon" type summons similar to how they are used in FF13 which allows each character access to an extended list of attacks.
CON: Story dialogue is just too long and drawn out between battles. I love a good story but I think 5 minutes of dialogue between battles is a bit much. I found myself busy clicking through because I couldn't be bothered to read it all. To top it off, the upper left menu shows a skip function, but you can't use it. Perhaps that changes later.
