After 2 days of play I must say I don't really like that game for now... Of course the lag is a huge issue, but that's not the only one.

Either you spam easy Missions to level-up all the day to gain 2 or 3 Levels, either you try the ones you don't have completed yet and... in that case, you spend all your time in the Infirmary... with only 2 Beds...

Your Officier Level is almost never displayed, and Upgrading Buildings is just a random fest seriously... Sometimes you need Level 6 to Upgrade something, sometimes 8 or 11 etc... So what? Should we take note outside the game to know which Buildings are upgradable or try all of them each time we Level-up?
And the Ressources Limits are also not displayed (you have to check them in different Buildings... facepalm)

Battles are... so ugly (in FKG they are not really to my taste, but at least the game overall is nice). Anyway, WTF is this SKIP Battle button? Of course I use it everytime, but, I mean, why should I load all the battle first before being allowed to click on it? That's a complete non-sense! If I want to skip the battle there is no reason to load the map, sprites, music etc.

I also don't know where is my Inventory...

To finish I won't mention the lack of informations about a lot of things (Divas, Trainees...).

I will probably continue few more days to be sure, but that's really probable I will quit it soon after.
