Thanks for playing!
I'm not sure what could be causing weird mouse behavior, it translates your desktop movement 1:01 to degress in both axes so it shouldn't be giving different sensitivities, I'll put in separate X and Y sliders if the problem doesn't go away.
I'm going to put in some more difficulty levels later that apply damage mods to the enemies, probably won't cause you to do less damage though as I think that's cheap.
Rushing around and cyberpunk are very much the idea. For now the map is really bright because I haven't put in the lighting system yet, when I do this map will be in the late evening rather than the middle of the day, and most other maps will be in the dead of night.
I want nothing more than to start again in C++, but I've come too far! If you must know, I simply found LibGDX to be very useful to get going with, after this project though I won't be touching Java again except for much smaller games.
