Epic Hero Wars - stick fight

I love the game and love what they are trying to go for! Though there are several bugs throughout the game. I've played for over a month now, and it's extremely difficult to actually progress in the game without watching ads for items. I've tried several times trying to register my own account, but it always says "username is already taken." I'm extremely frustrated, please fix this. But overall without all the bugs this game has. This game has a lot of potential! I'm playing on mobile btw.

Definitely NOT for a casual players. Game breaking bug right after start in tutorial. Had to reinstall. Game is kinda mess, nothing to explain anywhere, takes lots of time to do anything .. so much grind. Its daily and time based. You can do certain things only in certain days. There are only certain time windows when you can do it, if you miss it, you have to wait for another window to do it, like conquer .. pretty annoying. New quests in 2 hours .. you came after 3 hours, and new quests again in 2 hours, because you missed the window. Its kinda nice game, but very easy to finish, almost impossible to master .. but, if you will give it hundreds of hours, then maybe .. or pay thousands to the finish line .. which is current game style, but i dont agree with it. After a week i had nothing to do. Just sitting there, waiting to make upgrades which wouldnt give much .. just the last 2 are good. Funny thing is, bundle for 50 EUR is obtainable with just 3 EUR within the same game, same shop .. logic.

The game has taken my interest with it's progression, which gives me something to keep on playing for. But the server reaponsiveness pulls me away from the game, it's as if nearly everytime I'd see a "loading" in campaign, bosses, arena, conquest, etc. it'd take me 5-20 seconds of me staring at it waiting. Hope you can do something about this to reduce the time it takes, or possibly remove that waiting time at all.
