To be honest I think all of your points are fair. I experimented with camera movement a lot, and I agree that EVEN IN MY EXPERIENCE the camera was really jarring at the start, and I couldn't fix it in the time allotted. Later on it was easier because it would zoom out whenever the distance was <100m ... but something bugged that display out too, and now it's incredibly hard to see that display on big screens.
(In my personal opinion) I didn't really find the slopes annoying, but I didn't play test it that much with that variation of RNG so who knows!
I agree the hitbox of the turtle makes it feel incredibly unpolished - during programming, it was a ball up until the last 15 minutes, and it felt fine!
Thanks for the feedback, I really appreciate it :)
