Love the concept, sadly I think the execution is a bit lacking, but I'd love to see this game developed.
My problems with this game are:
-The grind is kinda awful, having a decent fleet and just clicking battle every minute is not fun.
-The basically infinite upgrades make me feel like I'm losing pvp because the other side just has clicked battle more than I have.
-The UI is a bit clunky when placing ships, but one can get used to that.
The positives:
-Even with such simple mechanics there is actually some strategy behind this games, with different builds, and counters.
-The progression works pretty well at the beginning, so the game stays pretty interesting until the first 100 or so levels.
