You think the encounter rate is to high? I thought it was fine. But I guess I based it on my own experiance with turn based JRPG games like Final Fantasy 6 and Xenogears. Well I could make a patch that lowers the enoucters a bit if you find it to unbearable.
Don't worry, there is no need to be that drastic. For most of the time it's not terrible, but there are times in wich I get 3 encounters in the span of 8 tiles. I've played worse, though. I'm probably just not used to random encounter RPGs
