a small bug: if you press ESC right before a level finish, the news screen appears, a bit blacked out (like the main menu should show) and you can't do anything.
I have found a pretty interesting bug: i went afk during a stage and when i was back i was defeated (obviously). But after that, each stage stopped spawning enemy units, so i win each stage in 22s using full cavalery.
