Its a fun little incremental, I found it all easy to understand , the only things I found a little confusing were
- I didn't realize I could destroy resources for a while
- The wording made it seem like smithy's boosted the resources not the gatherers
I also think having the prestige tree fully or partly visible would be better, you get so few upgrades per island that it feels bad to be gussing what comes next
I also think the island generation could be a little unfair if not enough wood spawns you have to expand quite a bit which screws you over later when you unlock iron and gold because there is not enough space for them to spawn, personally I would let people use boats even if they don't yet have enough for any upgrades so they can re roll bad islands
but over all I had fun, I would like to see more building types, maybe combo ones or different types of bonuses or effecting different areas, to make it so there are more interesting choices , maybe some things taken from catan , like roads or ports ?
