Good thing this game's achievement is a botd. Its the last one I need for beginners quest (which I thought I have already completed) but it seems I didn't notice this one.
In that level first room after I rescue the girl there is a glitch that allows you to fall of the screen if you ty to jump through the door back to the prison.
I managed to complete the game and get the hard badge. Here is my tip for the game: get archers. Lots and lots of archers. Let the frontline to your general and maybe also to polearm slayer and silent assassin (one of each is enough). A healer will also boost your whole army so its good to get one.
I take a look at the today's botd- "Unscratched victory, complete a level without taking any damage." Me: "This is going to be difficult." I click on the game. The game loads. I realise I got that achievement 2 years ago. Oh well...
