Usually I hate merge type games but this one actually stays interesting with minigames, combat, multiple forms of upgrade, and a nice UI that while confusing at first (due to what i can only assume would be translation errors) is easy to understand after a little trial and error. The only 2 things i seem to have trouble with are at first trying to understand some of the descriptions which seem weird at first and i can only assume its because of translation, and finding any of the easter eggs.

The game works perfectly fine for a few seconds before I get this pop up saying "the nucleus has been discovered" with my ID under it. When I click okay it kicks me out of the game. I don't know if this is a bug or if the servers are down but I can't seem to play it. I've tried deleting the game and re-downloading it but it keeps showing up. I've gone to Google to see what the issue was but nothing popped up so I can't find any solutions.

I love this game. Very fun, addicting, and I can play for hours. I think my biggest complaints are two things that are kinda only really one thing. I can tell this is ported from a different language, I'm guessing Korean since that's what the Cafe is in, but it's poorly done. I'm not sure what some things are meant to say. Also it'd be nice to have a description to each upgrade. Some are common sense but elaboration would be nice on some. Otherwise 10/10
