Hi, I want to share my personal opinion/experience on this game. You may not agree with it, but it is my opinion.
Firstly I know, it's beta. That's why I write this feedback in a hope, some things will get improved.
The first impression is good. The graphics is nice. Tutorial is OK.
Later on, I've noticed several logical bugs - or artificial limitations, that are almost against common sense - e.g. in the first sector, you know about two marble deposits, but the game allows you to have only one at a time. (I will come to the mining issue later).
Another issue is different sets building material - fir wood + stone, hard wood + marble, exotic wood + granite. For each set you need several processing building and after you move after certain lvl, you have only limited use for it (well you need it for well, farm fields and mostly mines - that are relatively very expensive). In the beginning a player focuses on building material production (you cant do much else) and end up tearing down most of the buildings in a few lvls just to repeat the loop later on.
Updating building + building licenses limit
I understand the limitation for building limit counts, however there is a problem, that you run soon out of licences and want to start updating. However even for the very basic building (like firwood cutter) you need tier 2 material to update (120 hard wood + 100 marble). The problem is general, when you are able to build tier 2 processing buildings (e.g. for marble), to update you need gold (that is extremely expensive to produce btw - you get some amount for Q, but that is nearly not enough to pay for updates).
Production cycles
I like the idea that a building placement affects the duration of production cycle. However this could be more explained in the tutorial. (e.g. for sawmill you do not to be near any cutter, just the warehouse).
Gold production
Later, you need thousands gold coins for upgrades, you can earn some with trading, but by far not enough. Gold mines are extremely expensive (like 1400 of each hard wood, marble and tools) and from the ore you will be able to produce only like 30-300 coins (depends on how well you time you buffs, I did not use triple buffs only double) PLUS it takes at least 24 minutes for a single production cycle of coin. (to upgrade gold smelter to lvl 2, you need 800 gold coins)
Mines, mines, mines depleted
From lvl like 20, the most common thing you do is mine renewal. Each morning, most of your marble deposits are depleted (it takes less then a day to deplete them, even shorter, if you have more marble mines on higher lvl - I had my marble masons on lvl 2 and I dared not to upgrade them further). Searching for mines/deposits takes long time and you cannot schedule it, so this is really painful.
Fun only to lvl 16
The tutorial ends on lvl 16, after that you get 100 gold for each new lvl and on lvl 26 you can start doing adventures. The production speed of military is OK - it is limited by you resource production (e.g. swords and beer) plus by free workers.
It is still a bit slow, but you can't wish to complete the island in 3 days. Still, the way from lvl 16 to 26 was long and I only endured it because I wanted to see the adventures.
On lvl 26, you get I free and you can buy another one from store. These beginners adventures are easy, but a welcomed change. I was disappointed to know, that these were probably the last adventures I had.
You send you explorer to find an adventure (initially it takes a day to finish). However (and sorry I am not shure about this) he always returned to me with only 3 map fragments. You can exchange map fragments for an adventure, but only from lvl 36 and above! So no adventure for a loong time. That was the final reason I am ending to play this game (at least for now).
In the current state you end up logging 15-30x a day just to discover mines/marble deposits, rebuild farms, if you are lucky and have so bandits left on the island you can hope for one battle a day (more likely every other day). Maybe the explorer finds a adventure map sometimes, but I wasn't lucky enough for that.
The game is in beta. It needs a lot of balancing, but there are some logical bugs, that could be foreseen even before the beta. The game lacks some goal and for now even a "chain" to hold a user in mid game. There is a lot of work ahead.
