Have played several games against AI opponents and in all games having great lag issues.
Edit: Having issues with online opponents too..

Sorry for late reply! Have you seen this again recently?

After the latest update game is almost unplayable because of the lag...

Hey yiannisM, we're aware that the last build had issues with lag, sorry about that. Blame an overenthusiastic artist! ;) We've taken measure to fix this and they should be sorted in a new build, soon.
