At first I was a bit lost because I didn’t understand what you meant by JETI, but maybe that’s just me and my grasp of the English language.
Combat is pretty fun although the AI seems to have some problems. Their aim is pretty bad and some ships keep sailing in circles forever.
I have to agree with other comments that the UI is a bit obtrusive. Specially the stats of your ship should be out of the way or at least as the player you should be able to hide them.
In a nutshell, Pretty chill and fun battleship game.
