I think I dismissed the game on released because of Region Locked. But right now, I'm playing it for at least a week now -- I got another source that made me install the game aside from GPS, tho I guess I did lose some interest before because of the gameplay genre. Merge system, it's quite boring and uninteresting to be honest. But then there's the Cats and quality arts that make up for it.
Now, moving forward. Despite them updating the game with some good stuff and bug fixes. There's still some bug existing that's needed to be fix like Rollback Bug because it's affecting the Newbie Pass where even if you have used 200-300 pcs of energy and merge items 100-200 times, whatever you did when Rollback happen everytime you got disconnected -- Newbie Pass missions is not counting it, with that happening completing Newbie Pass sometimes is hard due to the existing bug.
The game definitely needs a story along with some good QOL. Since the game demands a lot of energy, it needs some like Hot Time Rewards (Energy) like once or twice a day.
