Whew, that was hard! I’m a lot better at the pacifism-mode, luckily. At least compared to the other players on the highscore. 
The hiscores are very nice, and they definitely add to the game! Without them, I would probably not play twice, but they add a lot of competition - which is fun.
A nice touch is the tiny flags. Great! Now I feel really about beating someone, because they’re from Sweden or America. :
A small improvement to this could be to allow scrolling on the highscore, so we can view more than just 10 entries. Maybe 50, or 100?
The graphics of the UI are a little disappointing.
It doesn’t feel well polished. When I die, there’s no clear way for me to return to the main menu, for instance.
I can press “back” on android, and the menu comes up, but this menu seems weird and half. Why is there more space between the last two buttons, than there are buttons on the entire menu?
The “back”-menu then overlaps the gameover-screen. This seems odd.
For the gameover-screen, I think you should have split the entire screen in the middle. Highscores go on one side, and scores as well as buttons (including the “back”-menu (this is really just an achievements-button, and a main menu one)) go on the left. Currently, it looks crammed together, and the highscore just looks malplaced.
Did you implement parts of the UI yourself?
The achievements-screen jumps back instantly when I release my finger after scrolling “too far”- the LibGDX scrollpane would animate it sliding back, neatly. Why did you not use that? 
The loading bar in the beginning was nice. I noticed that it doesn’t quite fill out before the game starts. This is just nitpicking though. Maybe it’s just my device.
The options menu is a little weird and disorganized. Most of the rectangle shapes in your UI has cut corners, which is cool. However, the rectangle around the “Options” in the top is square. Why even put a rectangle around it? It’s a title, right?
Also, why is the font not consistent? The button-sizes are also not completely consistent, and this feels weird as well.
Why is there particles upon touch on all the menus, except for the main screen? Why leave it out for that?
Why is there an exit button? I take it most users just press home. Most applications don’t have a way to exit them other than that.
The last thing I can possibly complain about is that the icons don’t really match the rest of the game.
Gah, I’m probably not being fair to you by pointing out all the details. I do honestly think this is a nice game, and I’m only saying these things so you can make it even better.
I hope you can appriciate this, and not hate me. :persecutioncomplex:
