And for some reason, a strange phenomenon that couldn't—no, shouldn't—be happening to the Captain is occurring.

so far this game is good, i like the character, the graphic is well made and mostly every mechanic in the game are challenging but so far not to bad, but i must say to the developer can you gave us more reward inside the game because it felt for f2p player struggling to get the newest character even there partner, most of the game is already good it just we lack on getting more reward and it almost frustrating when we lose on some sort of character that we dont wanted. please developer consider.

I've played since its release and I had a negative opinion of it previously. Months later, I've decided to return to this game and I must say, I am quite impressed with the amount of QoL changes introduced while I was gone and my Sereniel team still remains a powerhouse. Of course, don't expect to achieve top of rift leaderboard rankings if you are not whaling because some characters are pretty much necessary for it. That's one of the few questionable parts of the game otherwise I recommend it.

So far on my experience really enjoyed game play. Character design, movement, story, how to progress. But the only bad thing is that how to accumulate source for upgrading was quite a hassle, the AP(aether point) that you used, you had to wait like a day to full. Just for 1 round it consume 20 point, in other word you can only farm for 12 time per day. (please shorten the time). Of course there's an item for it but only1/4 being provided if used the item. So yes that's the only worst experienc
