I concur that it clearly felt like a mobile game to me - especially as some long clicks might have ended the turn early, I think (which was not documented either) ^^
I didn't pay for the game, so I figured I could at the very least give an honest review to help. And who knows ? If it improves, I might be tempted to give something - but, for now, I never felt engrossed enough to want to try and push forward to finish a game, I saved around turn 120 and didn't come back.
If you update it, I'll glady give it a try to see how it improved !
