My gripe about the mouse movement and the turning was that when I hit the border of my screen I couldn't continue turning that direction because the mouse hit a wall.

Yeah ok, we've chatted a little on Discord so I know about some of the struggles you had with this and can totally empathize. Obviously there isn't much game here yet, but I will say that I was excited to be able to navigate the world in this isometric perspective and the idea of placing various tower types kind of wherever was intriguing. You should definitely keep working on it if you aren't too over it, maybe take a little break and give it another look?

Looks like a good start to a game but not much working that I could test at the moment so hard to judge. I played it on my youtube and left my feedback while playing to maybe give you some pointers. You can check it out here if you want.
