Rating of 2 heroes.

I can't rate it higher than four. The sphinxes and caves with monsters are confusing, and they can be solved by save/loading. Also, the Knights lack a decent level 1 monster. How can you spend gold on warriors whose stats are all equal to 1? If, for example, 50 peasants couldn't deal less than 50 damage, that would be a different story. But they can deal even less.
