Good game, but I have many suggestions
-The most annoying thing was the error message in the tank editing screen. The message slowly faded away, and it took too long for it to do so. That's true for any menu or message in the game. My suggestion would be to either speed up the delay time or make it so that if you click, it skips the transition.
- A combination of basic cannons could make most of the guns. Sometimes the firing rate was faster in the others, but it was really hard to compare the firing rates of two different weapons. Since it is one of the most crucial aspects of the gun, you should write it in the weapon description.
- Every time i made any small modification, I would have to save it as a new ship. Even if I gave it the same name, it added it as a separate place in memory. My suggestion is to make it so that it would be like a word document: save & save as. That is also probably why this game takes so much memory space.
