Hi, Does anyone experience an issue where the game does not save your progress at all?

For developers: is this game like Antiyoy for android? Thank you

I really want to know how to unlock the 3 stars on a level. Does completing the lvl faster is better than upgrading many unit ? Or just spamming lvl 1 army is better ? Or killing a lot, avoid being killed ... I didn't found any info about your system of stars, please explain me =)...

After beating the first campaign, I noticed the option to go back and play they on hard or extreme difficulty as well. I tried, and it crashed out. When I went back in, those options were gone. Is there supposed to be four levels of difficulty?

Right now, mini-map tracks units and huts only before I select it first time this turn. It make early mid-game quite hard to track, as every "touched but not moved" unit and "bought, but still with money" hut stopped to be marked on mini-map, even if they have actions. Can you change this behavior, please, to "everyone/everything with available action"? Or at least give us such option? Also, in my opinion, marks are too big. I would be glad to have 1/4 of current size....
