I played around 3 hours and can say that I got familiar with all game mechanics. Game is definitely interesting and playable, I like idea a lot. But if you are looking for playtest, here is my feedback about aspect which imo could be improved,
1. Having natural wonders gives huge unfair advantage, especially that map is generated randomly. If player or AI get 1 or 2 of them, that the whole game. I'd recommend to remove them or redesign their mechanic.
2. There is no motivation for player to build more towns. You probably want to invest and develop one strong town, rather than staying with 3 weak towns, which will be easily burned.
I was glad to see "No Cities" option but it seems not working. As for me, better to give only one town for each player and make map smaller to be able to have enemies in reasonable range
3. The winning strategy is to develop combat skills by building barracks and research. Once you have 50% block chance you are unstoppable. The problem that player doesn't have winning ways through investing into other skills.
4. Dragons, wolfs and wizards are useless. They deal 1 damage, while soldiers deal 3. Whenever dragon hits all enemies, you still have to make 2 hits to each of enemies. I think it would be better to reduce HP from 5 to 3 and make 1 damage for each hit. Dragon probably should be more powerful (like immediately kills 3 enemies) but with reduced probability (for ex. 5% instead of 25%)
5. Would be better to have direct correlation between people involved into combat and its visualisation. I don't understand why when I'm sending 5 people to kill 14 pirates I see combat 5x5 ships. Maybe introduce 2 types of people? E.g. soldiers and heroes. Heroes can be sent to ruins and fight with dragons while soldiers need to defend cities and fight with pirates.
6. I didn't notice any effect from morale. Maybe this mechanic needs to be redesigned or at least described.
7. Meat and ale - why they used automatically?? Since only usage for them is to exchange to fame, now you just motivating player not grabbing those until appropriate quest appear.
8. Sand is useless but seems to be more frequent tile. Try to play in mode with town at the beginning and see how much of initial territory occupied with sand.
9. Red/green bars appearing when action is tested is not very informative. I suspect that you try to visualise something like success probability, but it's not visible what was the result. Why not showing it with simple dice or score?
10. When my town is burned I'm losing all items. After such effect I'm losing interest to continue playing since you are starting completely from scratch. Maybe make items to be permanent? btw, I'm talking about respawn mode. If respawns are disabled all you need is to focus on destroying enemies and you can skip most other game parts which is quite boring
I think there are more balance, AI, map generation areas for improvement, but those which I listed seem to be most critical.
Anyway, it is just my opinion feel free to ignore and sorry for long post, just wish you to complete your game, good luck with it
