The hide feature still has a lot of potential, maybe re-think that in a different way that's not a power up but an intentional behavior that could be used to hunt ( both animals and humans) or to escape. Perhaps something you can toggle when near by a certain object, such as "hide behind a tree", etc...
On the movement side with the push out, the speed boost, and different speed up and down hills, the game feels way much better....great job, I'd suggest perhaps to consider also a short sprint (some seconds) on the above speed you have with a double click...cause sometime you need just a little sprint, and will make the gameplay even more dynamic, I beleive.
Example, you are walking at 2x speed, you double click and he will run for some seconds at 3x speed.
Also very interested in the rendering rewrite, let us know something about down the route. Cheers
