* I really like the user interface and overall presentation - it could probably do with some optimization to increase the amount of on-screen information, but that's probably all I would change there.
* Maybe it's just my machine or some other weird quirk, but for whatever reason it's a bit tricky to actually click on any/all of the buttons. When I hover my cursor over a button (and again, this is the case for all buttons) it appears that the game rapidly flip-flops between recognizing and, er... unrecognizing (for lack of a better word lol) that the cursor is over the button - in other words, the button rapidly switches between the "active" gold border and the "inactive" silver/gray border, and likewise it is only clicks that occur while the border is in the gold, active state that function.
* The difficulty curve definitely still needs some work. It seems that the first few raids are impossible to successfully defend against (although they barely do any damage either, so it also feels like it doesn't matter), and then within just 2-3 minutes raids become a total non-issue, and I quickly stopped thinking about them entirely.
* I'm sure this one is just because of how early in development the game is, but the mechanic of invading other nations is far too simple and straightforward in its current state.
* And, welp, that's about all I've got so far. I've already gotten a solid 15 minutes of enjoyment out of this game just from the basic gameplay loop, so needless to say I'm definitely looking forward to seeing how things progress as it becomes more fully developed and fleshed out.
