Heroes 5.5 WarGame Edition - Tactical Edition.

The point is that you can't just stretch the parchment arbitrarily; you need skills in working with textures for that (as well as for the arrows themselves). Reducing the size of the buildings is also not an option (I initially considered smaller buildings), because small buildings don't look good and make the layout more confusing. The main problem is the diagonal arrows, like the one from the town hall to the market (in this diagram). 1 column, 1 row (from the top) to 2 columns, 2 rows.
