Hey, thanks for your post
We did not have enough time to make an tutorial in game, so here’s an instruction on how to train the units.
To get friendly units you have to click on the training tile and press 1, 2, 3, 4 or 5 sea menu. But to do so you need to have enough food. If these conditions are met you should be able to train units
you get food from the food tile. All tiles cost coral to place, and you get coral from the coral tile.
The amount of food you have and coral you have is displayed at the top right of your screen.
I hope it will work.
