The idea is good, but the names of the upgrades are not very good.
P.S. Write down the characteristics of the creatures, the history of the race, etc.

History of the race:
One of the 7 dragon gods, Shallassa, created the race of Atlanteans, but for many years no one knew about their existence, and they themselves did not want to come out.
One of the sea lords, Rozzar, wanted to disrupt the established order and establish trade with the land dwellers. He formed an alliance with the mages. The mages created devastating machines that extracted fuel. Everything would have been fine, but fuel spilled from one tank and polluted the sea, and to make matters worse, a collapse occurred. The neighboring lord learned that Rozzar was in alliance with the mages and reported it to the king. A war began.
