The first thing I didn't like was the map itself. It feels like you're walking through a corridor, like in King's Bounty.
This problem disappears when playing on fan-made maps, which lack this corridor-like structure.
But what finally killed my desire to buy this product was the removal of the town screen!!!
A full-fledged, full-screen town screen with clickable buildings is promised to be introduced in a patch (although it will be 2D, like in H1-H4).
I think they could have worked more on the swordsman; he seems disproportionate! The skeletons turned out better, though!
Um... But there are no swordsmen in the game.
