yes, heroes is a great game...
and you did it quite well in wc3, because it's quite hard to make such games
with wc3.
But you have some bugs in there.
I couldn't use the 'pass round' here button. I ony clicked randomly at the position
of the castle and the I couldn't end my round. So I had to restart.
Another thing is, when I fought against a player/computer, the battle didn't ends,
when I won.
Also, I was quite disappointed when I've seen the battle system. It was just a
hack'n'slash, and no strategic battle like in the normal homm. But that's quite
hard to make, so I think this excuses it.
My last point is, that you only can buy/build things, when your hero is on the
circle at your castle. Would be better, if you would make, that you can always build
something, and only buy units, when the hero stands on the circle.
